Expect nothing and you will be fine. Seats are crammed.

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.
