great experience just at the end, we got in early and there wasn't anyone at the gate for 30 min so we had to just sit on the tarmac

It was all good, no delays which was a worry. All great

Website could be better with faster access to specific flight information and boarding pass once reservation is made. Not a fan of no seat selection on line. I had to consult gate agent each time to change seats on flights with lots of open seats. This cannot possibly be cost effective for airline. On plus side, Alaska seat legroom seemed larger than American. ns

I booked a round trip. I ordered a lunch going and a lunch for the return but got both lunches going. Could have been my error. Both lunches were good.

It was alright other than the changes in the Alaska Lounge. That and the migraine I had were disappointing. Other then that everything went well.

Seats were the least comfortable that I can remember ever having. Seat location just across from lavatory doors was not a good location to say the least. Wife has a back problem and to have a seat that is no adjustable for posture was torture for the three plus hour flight

Flight was delayed but it worked out fine. A woman was yelling and singing loudly throughout the flight. Unpleasant for everyone around

Your seats are so close I’m practically sitting in people’s laps and the micro thin mats on the chairs to reduce weight are atrocious in comfort

My flight was lovely and comfortable. Boarding was seamless and the flight smooth. The staff was so wonderful each time I’ve flown with Alaska it’s been such a pleasant experience I recommend Alaska to all I can.

Alaska Air always holds passengers on the flight for at least 20 minutes as they unload the luggage. This is unpleasant. Because of the o time luggage policy everyone has to sit on that plane for an extra 20 min. Let us off the plane and stop this nonsense. Everything else was great. Thank you.

They we able to seat my companion and I next to each other. Plane’s temperature was very cool. Willl be more prepared on return trip.

Plenty of overhead compartment room. The seat choice option is horrendous as best.

Flight delays - issues with delays waiting for a gate in Denver

I booked through Hawaiian which was supposed to have merged with Alaskan but offered free checked bags and said there would be seat selection at the airport. This was not honored by Alaskan Airlines and they even went out of their way to say “we are not Hawaiian and Hawaiian cannot pick seats on our airline ”. They told us that we could not change seats and that all tickets booked through Hawaiian were “saver fares”. The staff was rude and said that we would be helped last after they take care of the customers that booked through Alaskan. Once we got on the flight in our middle seats they played a message that said they have merged with Hawaiian and you can book on either website which would have been funny if we were not so uncomfortable. All in all it was a terrible experience and I do not recommend that anyone fly Alaskan unless they absolutely have to.

As my daughter was boarding the flight they pulled her from the line and told her, after she had checked in and checked a bag, that she could not board the flight due to a fraud flag on the debit card used for the ticket purchase. The personnel would not allow me to speak to them, saying I had to take it up with customer service that was not present. They tried to get my daughter to purchase another ticket on the spot or get out. The customer service personnel were insistant that the personnel at the gate be on the phone which they would not allow. Would not accept payment from three different accounts and did not resolve the issue. Many conflicting reports about the source of the problem, the fraud department is uncontactable. The only good thing to come of it was checked bag arrived. Our family will not be using Hawaiian Airlines. Ever.

A cold sandwich would be much better than the warm gummy croissant.

Seats were so uncomfortable. Used to southwest so this was really disappointing. No wifi made for a long5 hour flight

It’s really tough when you purchase tickets and you are unable to purchase your seats, and just get random seats when you are traveling with someone.

Having enough fuel to get to our destination seems like it should be a given when you board a plane. Not in this case, delayed hours to refuel.

Almost everything was perfecto expect for entertainment. There are not a many options.

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

The international portion was good. Food and beverage options were good. The sustainable wooden eatery was less than desirable. Your Star Alliance partner ANA provided real silverware. I'm 6'3" & 198 lbs and felt cramped in the exit row. How can that be? Flight attendant all had a pleasant disposition which is always good.

Boarded from a very small gate at LAX. Staff at gate had us line up, then waited 25 minutes to board without a word of explanation. Plane arrived on time then waited 20 minutes for a plane to vacate our gate. Majority of bags arrived after 15 minutes but it took an hour for a small number of remaining bags to be off-loaded despite my “priority” bag tag.

The boarding process on the departure from LA was rather slow even though I was in Group 1. For first class, I was not expecting to have to pay for Wi-fi but I did and then the wi-fi was spotty. The entree was surprisingly good and so that was a pleasant surprise. However, once I got to Houston, it was terrible. Unfortunately there was bad weather but the constant gate changes for my connecting flight was difficult to manage due to having to navigate back and forth between different terminals.

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

The flight was delayed, they didn’t even have water for the toilets or for drinks

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

The flight had a delay but I made it to my connection. Flight was smooth overall

No screens or meal options. Freezing cold. Dirty seats. Left late.

Overall flight was ok. Flight attendant was receptive to assisting passengers with tight connections.

Terrible. Delayed my family flight for several hours affecting family plans

Flight was delayed and then my second leg was completely canceled. Had to get a refund

When I wanted to check in 3 hours prior to boarding time, the employees mentioned “a little over an hour delay” so I waited for an hour then I went to go look for food in the terminal and most people from that flight were in the same area looking for food. Finally I decided after food to check to see if it’s anytime closer and now it’s 2 mins until boarding closes?! What are you kidding me? I didn’t receive anything via sms about boarding now nor via email or on the intercom. I luckily made it through, barely, and then there’s no room for my carry on mind you I’m in the very first row so I had to place my purse in one further row back and my carry on sections down. Not sure who pays for better seats to get your stuff placed all over the plane but that was the worst experience I’ve ever had flying with anyone.

My flight was canceled I was promised a reginf still not received.

The worst service , the agents from the counter are really bad . Poor customer service . They didnt help me to get in the flight . I was on line when they close the flight without telling and I couldn’t board the plane . I will like to get my money back ey back because it was their fault. Really bad management , bad manners, bad additud

Canceled original flight and wasn't clear on rebooked flight. Had to pay for bags which was more than the flight itself. Normal help, drinks etc. you have to pay for. This is Not a low cost airline.

We did not get to go on this flight because it got canceled 4 hours prior to scheduled time. We received an email that it got canceled and then 10 minutes later we received another email that it got delayed. It was very confusing and the only options they gave us for return flight home were 12 to 22 hours of travel time. That was not an option for us since we were traveling with kids and school started on Monday. We ended up opting for a refund and booking a flight back with Alaska. The flight ended up costing us $1500 and we had to book a hotel for the night. We will never book with frontier again.

I fly Frontier often and generally don't have any issues. For some reason, the Denver to Houston's George Bush Intercontinental (IAH) flight always needs to wait on the tarmac in Houston because a gate is not available after landing. I've been stuck for as little as 15 minutes and as much as a little over an hour. I know only fly the Frontier Denver to IAH route when there is not an available flight to Houston Hobby (HOU).

Terrible Y lost my connection to Mexico, nobody of your company help me And y pay a lot of money for my baggage Until now I continue in the Houston airport I vneed you return my money

Everything was good, 20/30 minutes late waiting on a crew member. It’s hard to keep employees. Or serious employees I know. I remember one flight from Houston of Frontiers was almost 18 hours late. And another 4 hours late very poor. But I would rather be late and safe than the on the news. Thank you.
