I like the leg room. Coffee was so bad that it gave me stomach pain.

Read more about Alaska Airlines

I like the leg room. Coffee was so bad that it gave me stomach pain.

Cons: "Better business class seating, better food and in seat entertainment as it isn’t enjoyable watching movies on an iPhone."
Pros: "Alaska airlines staff from checking in to flying set the bar in service standards. I have never been disappointed with their professionalism and will continue to use their services exclusively when I can."
Cons: "Nothing."
Pros: "Crew was very service oriented. Appreciate their constant offer of water."
Cons: "Someone should know how to make your entertainment system run on iPAD. I preloaded your system before boarding. However, even though I can access your menu, I can not play any movies. The crew tried to help but no one could figure out how to make it work on iPad."
Pros: "The flight attendant was so amazing and observant that she noticed myself and classmates all wearing our alma maters sweatshirt and gave us the loveliest a shout out!! We were headed for our college reunion and had unintentionally been on the same flight. That was so much fun!!"
Cons: "Free headphones"
Pros: "Friendly crew"
Cons: "No screens on the plane...for a 6 hour flight. Additionally, the seats are close together."
Pros: "Staff was very attentive at checkin and gate. They were ready for me before I was ready for them! Flight crew was also great. Seats comfortable, plenty if legroom in coach."
Cons: "Everything was excellent - but having not flown Alaska, I was expecting something exceptional. Top rated US carrier, and inheritor of the Virgin America legacy, I expected something more. I've flown VA, and it was an exceptional experience."
Pros: "Always great crew on Alaskan, but this is the first time the pilot updated us constantly and I loved it."
Cons: "Better planning on Reagan and Seatac airports with their air traffic control."
Pros: "Smooth flight, easy on and off."
Cons: "Staff could have paid a little more attention to what the were doing. Asked 3 times for apple juice and got orange juice. By time I realized what he had given me, he was gone ☹️"
Pros: "The crew were very diligent in serving water and drinks."
Pros: "crew was exceptionally kind and helpful. I felt they really cleaned up, sanitized, even participated sanitary clothes and hand sanitizer to everyone."
Cons: "Nothing, perfect. better than expected."
Pros: "Crew was amazing before and after the flight! Delta really showed if the world isn’t doing well, that their staff will keep those problems outside the plane and keep everyone calm and safe. Thank you Delta!"
Cons: "Absolutely nothing. I’m going to join the miles points with Delta."
Pros: "Nothing about this airline. Will avoid flying through Delta if they allow their team to lie to their passengers. Both land crew and onboard crew were disrespectful to their passengers."
Cons: "agent boarding delayed boarding because she wanted everyone to check their bags. A flight that was leaving 2 minutes later than our flight started boarding before our plane. It wasn't that the 2 planes arrived at different times. The agent was just horrible. In the end, she lied to the passengers that there were no overhead space left. When I went to get my seat, most of the overhead space was empty!! I had to check-in my bag and my bag was damaged by the delta crew."
Pros: "Crew was exceptionally nice. Live DISH TV unexpected and appreciated."
Cons: "Flight was freezing. Crew was overly concerned about my tree nut allergy. Been flying for 40+ years and this was the first time any one has asked...appreciate it but they went overboard"
Pros: "The crew was very attentive and had great personality. They anticipated any needs we had."
Cons: "Not enough room with the seats if someone reclines in front of you."
Pros: "The crew was pleasant and helpful."
Cons: "The plane was an outdated jalopy. I thought the exit doors were going to fly off. This was in vast contrast to the 737 plane that we had taken earlier in the day for a flight from BNA to ATL."
Pros: "The plane was nice"
Cons: "I’m still sitting in Minneapolis so I would have liked to be at my destination. And I had to pay for the overnight accommodations."
Pros: "Entertainment was awesome. Although airlines are stingy with snacks, Delta had a good overall selection and very generous."
Cons: "Something that cant be changed overnight, however, there should be a little more Aisle space for folks pass through as my shoulder was getting beat up after every passing person and cart."
Pros: "Excellent leg room in standard seating. On-time with quick and efficient boarding process."
Pros: "Easy boarding"
Cons: "Half the flight didn't wear masks, crew didn't bother to enforce."
Pros: "Allegiant does a great job of turning flights and getting you out on time in general. The crew is friendly and helpful."
Cons: "The ticket lady was rude just nasty and upset for no reason."
Pros: "Flight attendants were great."
Cons: "Bag check agent could have been a little more friendly."
Cons: "on time flight. Accurate info on app. Correct seat assignments"
Pros: "Allegiant knows how to get people off and back on the plane ASAP. The last few flights I have taken we left early and arrived earlier than planned because of this. Crew was friendly. I like the fact the flights are direct and no layovers at airports."
Pros: "Efficient, direct flight, outstanding price, quick boarding, left late but arrived on time"
Cons: "Nothing. I did not try food or entertainment on this flight."
Pros: "Short flight and pilot was able to explain delay"
Cons: "Long delay due to many planes in front of us, no offer of water only drinks we have to pay for"
Pros: "Nothing to like!"
Cons: "Allegiant has an obscure boarding policy that shuts down online and in-person check-in 45min before departure. We got to the Allegiant desk 35min before departure to get our boarding passes and no luggage to check, and were told we missed the flight because check-in wasn’t allowed anymore. That policy should be made very visible and clear to anyone buying tickets on Allegiance as no other airline does that to passengers. We lost 4 tickets and had to buy tickets for a flight the following day. Horrible experience!"
Pros: "Glad we made it back."
Cons: "Flight could have been on time. Attendants in the airline could have communicated much better to give update on delay, but they did not give any information despite several times getting up to ask questions at the main check-in. Many of the passengers were very discouraged. Plane left nearly 2 hours late due to an unclear maintenance issue, paperwork and also no fuel put in the plane until all passengers we on board."
Pros: "The crew was super nice, they offer me to change my seat to fly with my sister."
Cons: "The pilot"
Pros: "Crew were amazing"
Cons: "WIFI please for the god sake it’s a transatlantic flight"
Cons: "Your seats are too small, but we know the airline industry is not gonna do anything about it."
Cons: "they keep using a very old 767: no personal entertainment screen, no USB outlet and absolutely freezing temperature. Most of the people put on their heavy coats."
Pros: "Smooth price getting boarding pass and we were anytime sit together"
Cons: "All good"
Cons: "My tray table was dirty. It had crumbs on it. The flight was on time which was awesome."
Pros: "Flight was mostly empty and it’s a short trip."
Cons: "The seats are extremely restrictive and in a aisle seat I had the gentleman sitting next to me with thighs touching and attendants brushing by me as I squished to left to avoid contact with him. Entertainment screen between center seat and window seat so I just didn't even try to look at it and mostly just leaned forward to have a little space. Also another inch or 2 was taken by person in front of me putting their seat back. With such restrictive space why is this even possible??? Flying has become ridiculous and I try not to as much as I can."
Cons: "We landed early but the plane was late 50 minutes into gate. Plane went pst our gate twice, just driving around the terminal."
Pros: "Got to San Antonio finally"
Cons: "Not having maintenance issues on the same flight from the prior flight to our airport then having more maintenance issues prior to leaving."
Cons: "The Boeing 737-800 did NOT have enough leg room for me. My first flight to Houston was very uncomfortable, even with an aisle seat. If I can, I will avoid this plane when booking future flights."
Pros: "I was able to change my seat."
Cons: "Five hour delay, no entertainment, no food... A really poor experience."
Pros: "Staff found us two seats together. Food was good."
Cons: "Email telling us about pre airport arrival check in and seat selection."
Pros: "The crew was nice once we got going - after 1.5 hr delay, not due to weather. The delay was per United's Capacity restrictions on a smaller plane: a 737. They kept giving offers to fly tomorrow, starting at $500 and when it got up to $2000, people really responded. Then, after another delay: gone"
Cons: "Communication was miserable. The UA workers tried, but really looked like they didn't understand what was happening. Too bad: wasted time."
Pros: "Good entertainment options but couldn't get them to work on my laptop so I had to watch a movie on a small mobile phone screen"
Cons: "Long delay due to weather. Got screwed by a change fee for a mistake I made on my original booking, no consideration. Good entertainment options but couldn't get them to work on my laptop so I had to watch a movie on a small mobile phone screen-website didn't request to download or activate DRM plug"
Pros: "the flight attendant was a little snippy with a couple of the passengers"
Cons: "need to change up the snacks a bit. Maybe offer 2 options? And they are so tiny"
Pros: "The crew was ok. The seats were far from comfortable."
Cons: "The seats were so close together and did not recline to a comfortable position at all and to be a flight over 2 hours is just plain ridiculous! I will definitely be putting United on my list with Spirit from now on. Choosing either of them for such discomfort versus price savings is not worth it!"
Cons: "The delay was horrible and the captain said it was because they needed extra sleep. I found this offensive as i was trying to complete a very long trip and was exhausted."
Cons: "Couldn’t control the temperature. It was freezing then burning up."
