FAQs - booking El Salvador flights

  • Do flights from Boston to El Salvador include my frequent flyer program’s airline?

    If you want to make sure you can add miles to your frequent flyer account when you fly to El Salvador, you can use KAYAK’s Alliances filter. So if you are a member of United Airlines’ MileagePlus, you can set the Alliance filter to Star Alliance to see flights with partner airlines, such as Copa Airlines.

  • Can I bring my dog with me on my flight to El Salvador from Boston?

    Many airlines allow pets in the cabin, but you should check with the airline about conditions and fees. For example, Avianca allows passengers to bring one cat or dog onboard, if the pet is over four months old, weighs less than 22 lbs., and is kept in a carrier that can fit under the seat in front of you, among other restrictions.

  • How many bags can I bring with me aboard my flight to El Salvador?

    The luggage icons on your KAYAK search should tell you what is included in your fare. Usually, Delta tickets each include a personal item and a carry-on. Typically, a personal item is a purse or small backpack that fits in the seat in front of you, and a carry-on is a bag that can fit in the overhead bin and is no bigger than 22 x 14 x 9 inches.

  • Will I need to go through the check-in process again if I have a layover between Boston and El Salvador?

    You may see a flight you like that has one or more stops showing red triangles by the stopover cities in your KAYAK results. This indicates a self-transfer, meaning you may be required to check in again during a layover, such as with some Spirit flights connecting with Avianca in Miami. To avoid this, you can use KAYAK’s Flight filter to filter these out.

  • How does KAYAK find such low prices on flights from Boston to El Salvador?

    KAYAK is a travel search engine. That means we look across the web to find the best prices we can find for our users. With over 2 billion flight queries processed yearly, we are able to display a variety of prices and options on flights from Boston to El Salvador.

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional round-trip ticket. You could then fly from Boston to El Salvador with an airline and back with another airline.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from Boston to El Salvador?

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

After a 5 hour delay waiting at the gate (3 delays adding up) with no clear reason provided, we finally boarded flew 3/4 of the way to Toronto then were turned back to New York. As we neared New York, the pilot declared that it was his fault, something to do with timing and him not being allowed into the country???? How could the airline let his happen? They had hours to prepare and make sure they had a crew available for the flight! We ended up in Toronto a day late with no sleep.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

Terrible and im avoiding them in the future. My initial flight was delayed causing me to rebook my flight and when speaking with the representative to rebook I explained this is the second time my flights were delayed and they did nothing to help me. I wasn't booked to comfort plus or given a voucher or anything. I was almost late for my meeting that I needed to attend on Monday because of the games delta played delaying my flights even more and putting me in the very back of the plane next to an extremely intoxicated passenger

Friendly flight attendants, smooth 8-9 hours flight. Economy seats are small and uncomfortable as usual.

Flights on time. .Ride was as comfortable as can be expected in steerage. Luggage arrived at destination. Attendants were fairly friendly.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

The WiFi didn't seem as fast as it normally is

I upgraded myself to Business Class at the last minute so I had a DREAMS window seat. Seeing as I've never flown Business before everything was novel and fun for me and it made the 7 hour flight much more enjoyable for sure.

It was reasonably comfortable trip considering its duration (7 hours). Crew was very good and friendly, seats very more comfortable than other planes. Only negative comment would be that the bathroom light did not get its full brightness 🙃

It was good, plane is a bit older so seats are somewhat flat

Well the airline was fine. The only thing is I was charged for a checked in luggage. But when I reserved the ticket it showed a check in bag allowed. Who can I get in contact with for reimbursement.? The airline said I had to speak to whoever I booked ticket with.

I loved my experience. Very safe, Very informative and very friendly.

At JFK the Security line was extremely long and few checkpoints open.

Check in person said there would be lunch. We were first class passengers and lunch was chips.

Flight attendant -José? - was over the top friendly and professional. Beautiful new plane with lie flat seats in Business (worth it!)

Horrible food. No wine or any other alcohol is served on the flight. Water is not served often and they refused when I asked for water in two cups. On the other hand, both going and coming back flights were on time.

Very good flight and crew Food was a surprise on a short flight

The gate was too far away for the connecting flight

They switched out gate from terminal 1 to terminal two ten minutes before boarding. So we had to make a 20 min crazy fast walk to a different terminal. Then we boarded the plane and waited for over 40 minutes until push back. Brutal

Compared with other carriers business class for an overnight was not worth the extra expense.

Seats were comfortable. It’s was so cold and very uncomfortable. I paid 2000 miles for wifi service that was choppy the whole flight. Would like to be reimbursed for my miles Food was so disappointing. Three cold and terrible meals for $3000 round trip. This needs to be better.

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)

Excellent, professional, actually on time which is rare for late flights. Decent food. I love the new neck pillows! Nice, simple upgrade from the old ones I wasn't sure where to put. I wish they would allow more time for rest. It's a red eye 7 hour flight and meal service was about 3 hours.

We boarded but then sat there waiting on some missed connection people to get on so we sat for about 15 minutes for that. Then we sat again because the passenger manifest was wrong and they had to figure it out before we could leave. That took about another 20 minutes or so. The crew was working hard to figure it out so it’s not their fault. It ended up being a system glitch where someone was upgraded to first class while another person was also in the same seat and it just created a mess that took a little while to figure out. They literally went to every person on the plane asking their names to see who was sitting in the wrong seat. I also hate the entertainment that must be watched on your phone or tablet. Just give us setback screens. It’s so much better. Almost every Delta flight has this now and it is so nice to have them. The crew did a great job. I have no complaints from them. They were very hard working, even with the mishap and a disgruntled passenger.

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

Flight was cramped with every seat taken. The food was fine, nothing crazy to write home about. The plane felt dated and needing some TLC, the button for the window shade didn't work and there were no AC outlets to use. When communicating with staff all except one nice lady never seemed happy to help me almost like I was bothering them when asked for things like a glass of water or a snack. The flight was overall fine. It did what was needed which is get me from point A to point B. But it certainly was not special. I don't expect much in economy but I believe economy on a host of other airlines is more memorable and better experience.

No food/snack served during the flight. Crew wasn’t interested at all. Flew American First but flying low cost with Ryanair is even better

Wonderful crew and early arrival to our destination. It was so nice to have free wifi access and movies too. Thank you!

Very friendly and efficient and smooth boarding. We were even way early arriving at my destination. Thank you.

The trip was very smooth and they provided great customer service

The plane was late and then sat on the runway for almost 45 minutes before taking off.

Wonderful as usual except for other guests that were unruly and not kept in check by the Crew.

The flight was initially delayed, then cancelled. American Airlines says the cancellation was weather related, though the actual weather was not bad in both Washington and Providence and between. There were very few cancellations that day. In fact, AA2120 from Washington, DC to Boston flew with a minor delay at about the same time. So, the weather somehow affected only this particular flight AA5230. The next available flight was the following morning. The American Airlines refused to reimburse accommodation (hotel at DCA)

I have long legs, my foot was out in the aisle and when a flight attendant came walking by and I didn't notice, instead of saying "excuse me" or anything like that, she kicked my foot. Extremely rude

One bottle of water and a package of cookies for comfort plus. We had to literally beg a flight attendant for an extra bottle of water later in the flight due to feeling dehydrated.

Fine. On time, cabin service was fine, bag arrived. All good. Flying into DCA so did not collide with any helicopters, which is also good. Horrid incident that could have and should have been prevented.

There isn't much space in-between seats and even water needs to be paid for during the flight.

We did not know about the bag fees until check in. They are way too high. It’s insane. We also had a huge delay and everything costed extra which was very annoying.

Boarding was somewhat confusing in that the wrong messages were being displayed at the gate. It was somewhat annoying that I got off one flight and straight onto another (from the same gate), but in between they re-checked my hand luggage and made me get rid of my water (which they charge for on the plane). I was sitting in their 'Plus' seating, but the leg room was still too small to be able to sit square. The food options on the flights are pretty cheap quality (but not price). They got me from 'A' to 'B' on-time and for a relatively good price, but the experience itself was below average.

Lounge for business was closed. Boarding was rush and stand by. Seat for business is just the middle seat blocked and some more leg room.

Flew with our two children. Paid $380 to check two bags (one was overweight). They then left the bags behind on Sunday, December 21st, with all our family’s clothes and family Christmas presents. When we arrived at our destination they told us the bags had not arrived, and they thought (but didn’t know) they were still in Boston, but that there’d be a flight the next day and the bags would arrive the next day. The next day we found out there was no flight, now we’re hoping we get our bags before we fly back out. Meanwhile, trying to get any engagement or accurate information is a waste of time. The folks at the call center are just gatekeepers, who can’t connect with any departments that actually do things to solve a problem. Getting information is made deliberately difficult. My biggest regret is that I’ve had a number of awful experiences with Avianca traveling between the US and Colombia, and still let myself get suckered into buying these tickets because the schedule was great. Never again.

We were not aware carry-on bags cost extra until we arrived at the airport so, we were charged $240.00 for two small carry- on bags! There was a substantial fee for drinks and snacks. No wifi, or other entertainment was available. Waiting areas were crowded and uncomfortable.

COP 7,000 for a cup of mediocre coffee. I thought I was on Spirit Airlines for a minute. Otherwise the flight was fine. Nothing exceptional to report.

please see previous response; it covers the whole travel trajectory.

I enjoyed it! In that case, I should have been offered this choice. On my first trip to Miami, I was asked to pay $320 for my luggage just for getting it totally broken. I cannot accept this situation at all!!!!

My whole return flight itinerary, 3 flights, got canceled without any warning to me because I missed one of the earlier flights 3 weeks ago
