I bought tickets MONTHS ago for a flight that left SAN at 14:30. That is what it says on our tickets. I was never notified of any time changes. During online check-in. I discovered the flight time had been changed to 15:45. This was unacceptable and had I been notified, I would have changed flights, or airlines. That departure time was unworkable with our plans. We called Alaska and asked for an explanation. They said flight time was changed 11/08/25. No proof of notification could be offered. We asked to be moved to an earlier flight. After much pleading, the rep said she would allow a “one time exception..” While I appreciate being moved, this was YOUR fault Alaska Airlines.

SBP to PDX 2/17/2026. One person ahead of us at the counter. One ahead of is at TSA. First to board. First row, first class. First to be served. Food and service very good. First off the aircraft. Flight was nice other than some moderately hard bumps on climb out (please find a way to control that!). Air Force landing (none of that Navy slam you to the deck stuff). Wheel chair at the bottom of the ramp waiting for my wife. Luggage out quickly, walked right up to the parking shuttle bus. First stop on the bus. I like the EMB 175 aircraft. This was as close to a perfect flight as I will ever see. Bravo!

Santa Rosa Airport is the best! Glad to have experienced it.

I love Alaska! We arrived on the later side without seat assignments only to find the had oversold the flight by 1. The attendants worked extra hard to find a way for our party of 7 to stay together and we made it on the flight! Loved the free WiFi also!

The plane not having any overhead bin space was inconvenient. Anytime my luggage has to be checked it ends up covered in scratches and that’s not covered by the airlines for replacement/repair. The WiFi did not work or was not offered for the flight from Seattle to Vancouver.

Delay for switching planes. Then delay after delay (mechanical) after boarding so that we were almost 3 hrs late, getting in at 230am. Crew was good.

The room for legs is adequate for a 6’ tall man and the flight was comfortable. The cabin is clean and the crew is very friendly and pleasant.

The he whole flight was very smooth on every aspects.

Due to plane delays on both legs of my flight home, I had to be rerouted from Santa Rosa to Las Vegas on Skywest and then to DCA on American. SkyWest airlines sat on runway in Las Vegas for 20 minutes waiting for gate to clear. My boarding pass for American that I was given by Alaska was incomplete and the Las Vegas airport lacked signage and departure boards. I barely made my flight bc it was so confusing. American Airlines has a much better wireless connection. I’ll never fly Alaska again. It clearly has problems.

I paid for wifi and it never worked... it was miserable. I couldn't access my shared files to work on the plane, it didn't work on my phone. I paid for nothing but frustration and continual refreshing, hoping it would work

Flight was smooth. We boarded early and left Grand Rapids about a half hour ahead of schedule. We then arrived in Lakeland about 40 minutes early. Flights attendants (3) were welcoming and pleasant. Wish we would have at least been offered to buy a bottle of water. No beverage service at all.

I really liked the young man who checked me in and took my bags! He was so kind and was very helpful! I told my sister about the great service and him and she said that is why she flies Avelo Air.

The flight was delayed by a lot and the seats are pretty tight

Surprisingly was one of the better flights I’ve been on

Short 2-hour flight, we took off on time, ETA was earlier than stated, no interaction needed with stewards, no food, no entertainment on such a short flight.

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.
