Planes are aged. The wifi is unreliable and on many fights, no-existent. The flight attendants were very good.

Planes are aged. The wifi is unreliable and on many fights, no-existent. The flight attendants were very good.

I had a wonderful flight, but the only thing that annoyed me was how crowded TSA was. I still believe airports and all planes work together to bunch everyone together to drive up cost.

Easy to book and to get check in and get on and off.

The last 30 min or so, they put the heat on full. We thought we were being basted.

Excellent experience. WiFi worked on this leg of My trip

Flight was great, but golf bag never made it until later in the day. Even though I had a nonstop flight it was placed on a different one. They made it right with flight credits and I was able to get it the same day.

It seems as though the provisions are even less. Although SWA used to be an economy Airline, that isn't really the case anymore. I paid over $700. for a round trip to Denver and I could have flown just about any airline for the price. The drinks are now in a 6-ounce cup and with ice I'm sure a can would fill more than 2 cups. However, I am very proud of SWA for using paper rather than continuing to contribute to the millions of plastic cups being used each day. I've thought of this fr many years and am so glad to see it come to fruition, if not by only SWA so far.

Exceptional crew! Friendly and professional. Pleasant attitude and treated everyone with respect.

Service was great, boarding and exiting went smoothly, and the flight was very pleasant.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a not a great airport.

The plane was clean. The flight crew was friendly and helpful. The flight was smooth and the pilots kept everyone informed of our status, etc. It was my first flight on Alaska Airlines and it was great. I'll be choosing them again in the future.

On time boarding, plenty of overhead baggage space even for Group F, on time departure / arrival.

Like - Staff was GREAT. Friendly, efficient, kind. Dislike - nothing at all I'll be flying Alaska again in a couple of weeks - long distance.

i liked that all seats had usb ports and a plug

Good but a boarding pass for my return flight was not sent to me.

Not sure why the counter agent's couldn't have helped us with our flight change and only gave us a number to reservations. I thought their job was customer service, not "call this number"

It would have been best to have a direct flight from Reno to Seattle.

I really wish there were TV monitors. I don’t have a mastery of computers, so I was left with a six hour flight, and no entertainment.

The airline was great. What was annoying as hell were the inaccurate emails from KAYAK telling me the boarding gate changed and the date of my flight was 1 day later then the actual flight 😡

The AC was running on the plane when its 40 degrees outside

I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Good and consistent Printer in lounge did not work for me :(

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Delayed in taking off because no flight crew. The in seat entertainment was working properly.

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

Bottom seat cushion is almost non existent. Very uncomfortable seat.

Delta was great the entertainment was outdated. Screen was very small and didn’t work.

Terrible landing. Uncomfortable seats. Great cabin crew-helpful and pleasant!

Tight fit in middle seat but OK for short flight. Crew was more interested in talking to each other than helping passengers - strickingly dissappointing. DAB is a great airport. New Haven sucks! Excellent value for the .

Avelo is definitely a budget airline and you get what you pay for. The plane was packed and the seats were not particularly comfortable. Staff was very nice and both of our flights were on time. The one thing I wish I had known was that the staff does not show up at the airport desk to check your bags until two hours before the flight. We had a 4:30 flight and had to check out of our hotel at noon. Since we have lounge passes we planned to check our bag, go through security and hang out at the lounge until we had to board. But because we could not check our bag until 2:30, when the staff showed up, we could not go through security and access the lounge. Passengers with boarding passes and carry on luggage would not have this issue. I might fly Avelo again but would only do carry on or plan to get to the airport no sooner than two hours before check in. And I would not recommend a long flight on Avelo since there is no food or entertainment and the seats are not comfortable.

No food or entertainment, but flight very comfortable and on time.

Baggage claim was barbaric at Wilmington. I realize that this is a startup airline but if they hope to grow or even survive they need to upgrade this airport. There is no automated luggage carousel and at times you are not only fighting your fellow passengers to get to your bags but also passengers coming in from other flights who cross right in front of you

No frills, i.e., no drinks or snacks. One is charged for everything. The cost really adds up. The crew and flight attendants were excellent and very pleasant.

I always walk by a pallet of Avelo branded mini bottles of water on the tarmac, but I’ve never seen them in flight. Yup, not even water offered on a 3 hour flight. No wi-fi onboard. We just watch the flight crew on their phone for 3 hours every flight. At least a mid-flight trash pickup would be great. Better than my last flight, but they only could have gone up from there. Don’t use for business or ticketed vacation like Disney… too unreliable.

You get what you pay for. The plane was dirty and the seats were awful.

Nightmare airline. Avoid Avelo. Understaffed at check-in with long, slow lines. Inexplicably had two flights and only one plane. Not weather or maintenance related apparently. One was supposed to go to Myrtle Beach and one to Orlando. I imagine someone thought it would be better to fly the available plane to Myrtle Beach and back and then go to Orlando since that round-trip was shorter. This didn’t account for the human factor of an end-of-week Orlando flight being 85% Disney passengers and putting the flight on a six-hour delay in New Haven airport… which, if you’ve been there, is tiny and has nothing to do for 50 kids excited to get to Disney. This delay was announced at the time of departure. No one realized before the time of departure there was no plane on the ground? And no one thought… hey I think the Myrtle Beach crowd might be a better one to have wait if we’re going to make a choice here (mind you the initial inbound plane was coming from Orlando and supposed to be out aircraft… they literally said let just grab this plane because it’s here to get this other group out at the last second). There is/was zero customer service desk for Avelo in HVN and there were no updates/announcements throughout the day. Plane still gets back late and we finally leave. No wi-fi on these planes, no snack or even water. I know this is budget airline, but expected at least a water after 8 hours of travel day. This should have been offered in terminal too. We land… hooray. Would you believe there is no ground crew to get the plane in to the gate… for 27 minutes. 27 minutes!!! At this point the rental car center is closing in 10 minutes, kids on the plane are crying again, and everyone is talking about how they’re never flying Avelo again. Finally get off. Bags are out at baggage claim right away (finally something right?), but they’ve stopped the carousel immediately and there is no baggage service rep. People are climbing over the carousel to get to the far side (if you’ve ever been to MCO you’ve seen it) because obviously they just stopped it immediately once all the bags were out. This airline is a dumpster fire. Icing on the cake was that while everyone was stuck in HVN, they were setting up for a celebration of their millionth passenger tomorrow. I bet 995,000 of those will never fly the airline again. Don’t fly Avelo. You’ve been warned.

Airline was the only available airline during the Southwest cancellation. It was easy to book. Lowest available fair. Convenient airports. Everything was great. Problem was, they didn’t release what gate flight was departing. The woman at the ticket booth didn’t know which terminal they were boarding and wanted me to wait in 30+ minute line versus telling me to look for flight kiosk. Burbank gate was packed. Otherwise the flight was perfect!!

Best part: It’s operated by All Nippon Airways. It’s quite literally comfortable, reliable and respected from boarding to landing each and every time. It’s perfection without extremity in lavishness — it’s how flying should always be!

The flight attendants were unhelpful. It was a packed flight, and usually a flight attendant would help find a spot in the bin for your carry on or shift things around. Neither made any effort to do so. Also, I had to then check my bag. I was told it would be on the carousel in YYZ, but it came up on the jetway. So lucky I saw others standing around for their bags. I would have walked straight past this and on to the carousel. They could have at least told me that they had given me wrong information. Very unsatisfactory.

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

The check-in process is not the best They should have agents in site to help with any problem especially a rebook. Why does one have to get on the phone when there were at least 8 agents around that could have help?! Flying is stressful as it is and having someone willing to do their customer service will ease some of the stress.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

boarding was uneventful. Snack was pathetic. A tiny fruit bar. Entertainment was limited to just select movies on your own tablet or phone. No live TV. I recently flew Jetblue and they had unlimited snacks and live satellite TV the entire flight. My seat was an exit seat, 20A. It was super uncomfortable. It felt cramped and the middle seat was taken up by a large woman who pushed into my shoulder and arm. Horrible flight.

They canceled our flight and left us stranded to figure it out

Cabin was pitch black, even during meal service. The reading lights for seat 2E/F did not work, and seat 2E did not recline.

Long wait before take off without an update for 20 minutes. Flight was good otherwise.

Plane still had screens for watching movies. Good selection too.
