Avelo provided exactly what I expected. They are a low-cost option with no frills but the experience was comfortable and the staff was great! I will be using them in the future for trips when cost is a priority for me.

Avelo provided exactly what I expected. They are a low-cost option with no frills but the experience was comfortable and the staff was great! I will be using them in the future for trips when cost is a priority for me.

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.
