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.

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

Typically I give delta excellent reviews. Our flight was delayed 2hrs, I was one of the fortunate ones who were able to get to my connecting flight. Also, annoying that on the connecting flight boarding personnel make me put away a small bag into my carryon. It small enough to put in back pocket seat, why hold me and the line up to just push it into my carryon.

Logan airport construction meant that boarding was chaotic crowded and delayed

Everything was great. Great service, excellent communication, and early arrival

We were forced to wait nearly 50 additional minutes before leaving the terminal.

Free Wi-Fi is good. That’s all - food mediocre, unfriendly crew, poor communication after trying to file a claim for my lost bag, which Delta didn’t even know was lost until I told them.

Delta flight attendants poorly managed the boarding process and overhead storage. My bag was checked last minute and no claim ticket was provided. My bag is now lost. Complete incompetence by all flight crew involved.

Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.

Customer service at the gate in the flight was exceptional. On time. Aircraft and seat was decent. Thanks Delta. 💗

It was terrible, if they ran flights on time it would make a big difference.

Boarding groups were called up in Spanish only. Luckily I know some of the language. They gave out grilled cheese sandwiches and a cup of fruit. I was very disappointed. I could only eat the cup of fruit because the only other option was vanilla pudding. The entertainment system and seating were great though.

Everything was smooth and crew was very polite and friendly.

The flight was 6 hours delayed due to equipment problems, I had to spend my night in the airport terminal in tight quarters. A bag of chips was all they offered, Then I missed my connecting flight and waited another 2 hours. All in all that trip took me almost one day.

it was great! Boarded on-time, reasonable leg room, pleasant staff, decent food. The only thing is we were directed to Terminal 2 when the gate was actually in Terminal 1. Smooth ride. Landed early. Got off plane easily and quickly.

Crew were all excellent. Wheel chair access for my parents was very good, although it took some time. Plane was ok but entertainment system did not work. NO WIFI on plane so could not get other things done while flying or listen to my Apple Music on my iPhone.

I like that they served a mail, I’m not sure about the in-flight entertainment. I didn’t really check. staff helped me with my luggage. Smooth boarding smooth takeoff smooth flight

So many hours of flying without salty food is a shame and the fact that they want to sell it to you seems like a rip-off

Copa definitely offers better service and price than other airlines.

Copa delayed the fight three times. We ended up flying about 24 hours after the original time.

This airline doesn’t five and dime you for everything. I do think that a checked bag should be included in every fare.

We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again

horrible website for checking in- no option just to write the passport number; ludicrous

The planes are so dirty! Food crumbs and finger print smudges, Dust over the vents and carpet stains. It’s disgusting.

Everything good until we waited for jet bridge at SFO. Then pilot gets on speaker & said it won’t reach plane- too short, need to go to different gate. Then 5 min later, adjusted plane/jetbridge & all ok?!?

Nothing, whole flight was a nightmare, was forced to check my carryon bag at the gate, staff was rude and unprofessional

David went above and beyond to make our flight the best that it could be

Was a pain having to leave the plane and reboard but glad the plane was fixed

How badly can you screw up baggage claim? We were told to go to baggage claim too for our bags from this flight. Another flights bags were there. They finished up. More bags from a different flight arrived. Our bags did not Finally the baggage claim belt stopped working and and are flight was still listed on the arrivals for that baggage claim 2. And then nothing It turns out that they had been delivered not only the United baggage claim but far away on a Delta baggage claim No I never told us. It was only the people looking around who had been on the flight But I’m sure there was plenty of time for the employees to raffle through the bags and steal whatever they wanted

The bag drop personal were not helpful. There was no food on the flight. Boeing aircraft, lousy as always. Everything else was fine.

We had to wait almost an hour for the wheelchair porter to be ready to pick up my mother. And when she arrived in Newark airport the porter was not there and she started walking with her cane and her poor mobility. When the Newark porter found her they didn't want to transfer her bags to the wheelchair for her.

Flight attendant walked away once they landed and we were forced to wait another hour after an already 3hr delay.

No overhead space so all carryons were checked. No internet.

The flight was on time and everything went very smoothly.

A thousand choices for movies and nothing to watch. I avoid 'R' rated shows and others with violence and sexual content, which results in a handful of flicks to view and I have them already.

I think I paid for an extra legroom seat and to be honest, there was not a lot of space available for my not very long legs. The flight was totally full and the staff did everything possible to meet the needs of all passengers. My only concern was for the size and spacing of my seat.

Typically, I am always impressed with American personnel. These you run into the rude old hags that are still around. I can tell over my 40 years of flying with them, they have made strides in improving their attitudes.

Two issues. The plane was old and dirty. The armrest looked like an old car that had the vinyl rubbed off. The Seats in these aircraft are about as hard and uncomfortable. I want to tour Italy for a month and I want to buy a one-way ticket to Thailand but I will not sit in the seats these planes have. It is seriously stupid how hard they are.

The seat could not recline. This was not indicated as such when I paid for the seat. So itvwad not the most comfortable ride. At boarding, the staff could have more pleasant even though it may be an intense time.

The seat could not recline. This was not indicated as such when I paid for the seat. So itvwad not the most comfortable ride.

The meals were mediocre and the alcohol selection was poor.

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.

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!!!!

They charged me $120 to check one bag and then charged me another $120 for a carryon. Ridiculous!

I was surprised that they didn’t offer drinks at least even though it was an international flight.

Kiwi is the worst, I couldn’t flight for work, Kiwi kept 100% of my money (they didn’t even return the taxes) I will not buy with kiwi again

The airline doesn’t provide nothing To their customers. No water , no food , no any drinks, no any kind of entertainment for free or at least paid with money cash currency . They sell some basic goods only credit card . Shame for an old international long distance trip. Never again .

$120 for a carry on bag !!!!!! Insane. Back-breaking seats. Do not recline. Food service is a disgrace. They give only water and a salty snack. Everything else has a price.

Our flight from BOS - BOG was delayed 10 hours because they were waiting for a Flight attendant to fly from Miami. They lied and said they would give us food and hotel. That was a straight Lie! It never came! We were in the airport for 13 hours with Two babies. We were on the plane 7 more Hours. When we asked to get diapers from our checked luggage, Jorge in Boston told my wife she should have planned better. Meanwhile, the 10 Avianca Employees Sat there and did nothing for 13 hours. Yes, we planned for 10 hours with the wait and the flight, not 20 hours JORGE! If this was an American company we would have got a refund! But they are not up to American standards. The kicker is they apparently needed the 3rd stewardess to serve the food. Guess what? It was 4AM when they tried to serve the FOOD! Everybody was asleep by then! Ridiculous! Never Again!

The fees for baggage were outrageous. $130 for carry on and $150 for check in for an international flight. The seats did not recline. We were not even offered water. Had we known all of this, we would not have booked Avianca at all.

My fly was cancelled so i run to the airport and fight for my fly Thank god at the end was good
