Great crew, smooth flight and landing. Wish they would offer Dr. Pepper and a choice of flavors of pretzels.

Thank you still providing bags for vomit. My son had a migraine and needed a bag to vomit in and it was right there behind the seat in front of us. Thank you!

Flight was great. Boarding was crazy because another flight was boarding late next to ours so everyone was standing and in the way.

Awesome just like that we have a timeline flying Alaska.

All good! No entertainment on this new plane yet but ok for this short flight. Great on time flight! Thanks

These questions are hard to answer. It was not until I checked in that I learned my flight was going to Seattle for a connection and not Portland. I did not get notified, or asked, about this change by Alaska or Kayak. Thankfully I made this flight; but missed the connecting flight and it took me much longer to get home. A service representative for Alaska says this happens frequently with third party companies, like Kayak. Please please figure that out.

I got the last seat on the plane, in the back in the corner against the window, and I paid a competitive price for my ticket several weeks before the flight.

Personal demeanor not good on flight returning to LAX..Great and superb on the way to Portland

First time flying with any airline that has decent seating. Great experience crew was friendly and the pilot was as well.

Behind schedule. Lots of time on tarmac. Perhaps unavoidable. Better than crashing!!

Southwest is Southwest. No frills. If you're luck enough to get a happy crew (we did), then it makes for a nicer flight.

It was a perfect flight in all aspects! Both legs!

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

I liked the crew member who gave flight instructions on "in case of a problem:. The seats are so small that only a young teenager could sit in middle seat.

Great flight staff. Ease of boarding. Overall, very uneventful and easy trip.

Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.

I recently flew Southwest from San Jose to Honolulu. I was very impressed with the flight crew, especially the flight attendant in charge of the front of the plane. She came through the aisle at least five times for drinks and water, and two times for snacks. I have not seen such service since I flew first class. Also, for the first time, they gave us the correct baggage claim number, and the luggage came out quickly. I can't wait for Southwest to have assigned seating! I absolutely hate the Cattle Call boarding procedure and the mad dash to get seats and overhead bins. However, the boarding was efficient.

We had a nice flight. Boarding was easy, our seats were comfortable and the on board service was pleasant.

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.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

737-800 in first class was pretty dumpy. Seat had an uncomfortable angle, storage under the seat was blocked so even my very modest backpack didn't fit, power outlet was flaky. Weird tiny seat pockets that couldn't hold a gallon ziploc bag, emesis bag missing, etc. etc. No in-flight service due to turbulence. Crew was excellent, boarding was smooth despite a full flight.

Delta flight was on time, seats were comfortable, and crew was nice.

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

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

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

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.

it was so bad. I tried to board my flight from vancouver to saskatoon. And to my surprise they did not board me cause the flight was changed and no email was send to me. and on my boarding pass which i got from seattle says different flight. I did not knew anyone from Vancouver, air canada crew was rude, i asked for today flight but they were rude and i had early morning dental appointment in saskatoon. I was so much in pain and my whole day is wasted today. and i suffered alot. They did provide me hotel but they did not provide me any food. I am really really disappointed first time had so bad experience with air canada. I may think twice to book it again. If i can get any reply or any composition that would be great. Thanks

Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.

I was supposed to be on business class at first class from Denver back to Miami due to weather changes. I missed my connection and it’s put on a flight to Fort Lauderdale. Instead of honoring my business class/1st class ticket, they put me in coach, but there were two first class seats open. I think it’s absolutely disgusting that I paid for first class $1300 ticket and they put me in economy and they had to open seats available and I have still not been refunded the difference. I ended up having to eat a snack box instead of the meal I was supposed to get and did not get home till 2 AM so I think that’s a little pathetic that I had to live off crackers for dinner And my poor dog ate some cheese and salami. Oh yes, apparently when they switched me to the new flight they forgot to mention I had a service dog

Boarding seemed to be organized bedlam. For what ever reason, preboarding took longer than 20 minutes. Made the plane 20 minutes late taking off. Luckily we arrived on time. Flight crew seemed very friendly. Only slight turbulence.

The personnel were professional and friendly. The Boeing 737 Max 9 is too claustrophobic and was very warm at both airport gates, and still warm in the air.

While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.

get E+, a must for 5 hours flight if you are tall

The first flight was better in terms of the aircraft.

The gate was too far away for the connecting flight

Compared with other carriers business class for an overnight was not worth the extra expense.
