Airline reviews
Pros: "Timeliness"
Cons: "If alcohol is served on a short flight I recommend getting through drink service faster. I did not appreciate getting my beer at the end (because I was at the back of the plane) and 5 minutes later the crew asking for it back because we were landing soon."
Pros: "Timeliness"
Cons: "If alcohol is served on a short flight I recommend getting through drink service faster. I did not appreciate getting my beer at the end (because I was at the back of the plane) and 5 minutes later the crew asking for it back because we were landing soon."
Pros: "Bryan was my steward on flight 1402 from Seattle to Portland and he was so kind and helpful. Will fly again just because of him."
Pros: "Always enjoy flying Alaska. Especially like that I can get a good coffee or a good beer on every flight."
Cons: "Nothing."
Pros: "The crew were fine. But the flight was 2 hours late"
Cons: "Departure time; comfort in waiting area at Sea Tac"
Pros: "The crew was so nice and the flight was on time and smooth."
Cons: "The chairs were really uncomfortable and narrow."
Pros: "Aircraft was clean and comfortable. Crew was efficient and friendly. The whole experience was excellent!"
Cons: "There was lots of entertainment available but plain old music was not an option. What if I don't want to watch a movie or TV, just listen to music!"
Pros: "Prompt and efficient boarding"
Cons: "The plane was stifling/hot. The air blowing from above was warm. While it was cold outside, the plane was miserable. i realize that planes are consistently delayed/held due to runway construction in Seattle...and that's nothing Alaska can change. But boarding early and then forcing us to swelter?"
Pros: "To short of a flight to review. Staff was friendly."
Pros: "The seat was comfortable and the plane wasn’t over booked."
Cons: "I didn’t like that we took off an hour late."
Pros: "The flight attendants were friendly and professional and took time for a little personal conversation."
Cons: "Wouldn’t change a thing! I don’t always fly! But when I do!! I fly delta!!"
Cons: "For options none. No drink carts at all. Had coffee once after I asked. Poor quality entertainment. Just a huge waste of money."
Pros: "The staff at Delta are always friendly and helpful and they were able to squeeze me onto a very full flight."
Pros: "Quick boarding process and take off. Flight was slightly late but the staff expedited boarding and take off. Staff is friendly. Service was great. Beverage service was great. Baggage was quickly at baggage claim."
Cons: "Even though its a short flight better food options for First Class would be appreciated."
Pros: "I always have a consistently good experience on Delta. Everything was great."
Cons: "It was a Great flight. I always enjoy flying Delta"
Pros: "Crew is always friendly"
Cons: "Aircraft broke, had to route me to an additional three stops just to get me home and through the night. Also, still unsure of where my checked baggage is."
Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"
Cons: "Not really an experienced flyer. Overall the flight seemed good. No issues with airline or airport. Just don’t understand self-important people that feel compelled to push the overhead storage limits with their bags."
Pros: "Nothing to like when 1. you are arriving at your destination after 24 hours plus delays. 2. you paid Comfort+ class (not cheap) and are constantly pushed back in the Main Cabin."
Cons: "Actual flights flying on time. What a mess!"
Pros: "The flight crew were very nice. I needed help boarding and departing, and they were there every step of the way."
Cons: "Not very much room, no alcoholic drinks available, couldn’t connect to WiFi for inflight movie."
Cons: "Too much to write down. Start at the counter and work yourself to the plane. I hope you get it right eventually, I’ll be flying Southwest"
Pros: "Check-in started a bit late due to late arriving incoming flight but the crew at the gate as well as in the plane did their best to speed the process. Flight was smooth, lande ontime despite taking off nearly 20 minutes late. Captain kept us informed when, through no fault of American Airlines there was a delay at the gate. Overall well done in these trying times."
Cons: "It will be nice when things are back to normal and actual food is served on flights of 4 or more hours duration."
Cons: "There are too many announcements on the screen before you can start watching entertainment. It takes about 15 minutes."
Pros: "Great crew!"
Cons: "We paid for WiFi but it was not working on this flight."
Cons: "Entertainment. If the crew communicated with each other. There were multiple incorrect announcements."
Cons: "My tv didn’t work my WiFi didn’t work and no beverage service"
Pros: "Boarding crew in Spokane was friendly and very efficient."
Cons: "There were no snacks - they told us they “ran out” on the previous flight and hadn’t refilled yet."
Cons: "Business class - never offered food or drink for entire flight."
Cons: "The plane we needed for our flight arrived really late so our flight was then of course delayed."
Pros: "Was able to get on another flight"
Cons: "If they could have held the flight for 15 minutes, I would have made it. My flight from Spokane was late. Now I had to pay another $250 just for a crappy room for the night."
Cons: "The bathroom on the flight from Denver to Santa Barbara was the WORST EVER! I doubt it has ever been cleaned and the poor people that had seats near or at the rear of the plane should have been refunded their money having been subjected to the smell of an “indoor outhouse!” Shameful!!"
Pros: "The range of 'free' food and beverages (including beer, wine, and liquor was phenomenal, and the functionality of the 777 touch-screen was outstanding. Seating was also more comfortable than comparable flights on AA."
Pros: "I watched a good movie."
Cons: "The plane seemed old. Food was pretty lousy. Hummus was dry, crackers were stale."
Pros: "I liked the ticket price."
Cons: "The seat was very narrow with absolutely minimal leg space, and a carry-on bag was not included in the fare."
Pros: "Nothing, absolutely horrible. This is why I fly Southwest and Alaska Airlines as much as possible."
Cons: "Everything. Mechanical delay missed connection, arrived at gate to see plane being pushed off due to delay. They couldn't have waited 5 minutes? Multiple people missed their connecting flights within minutes. They kept us on the plane in Boise then deplaned and re-boarded. No coffee on flight."
Pros: "The crew were friendly & efficient, the flights were on time, & the gate staff kept us well informed of any changes."
Pros: "Poor customer service and not understanding."
Cons: "Don’t now it’s not the company’s fault it’s just the representative that I spoke to. I don’t know how many times I could explain my situation, and my English is not poor and I thought I was explaining myself clearly. Best think I could do is just say forget it I’ll take my $ 430 dollar last."
Cons: "A smile from the flight attendant and something other than pretzels in first class."
Pros: "The overnight flight made it easy to sleep most of the way."
Cons: "I didn't like getting woken up in the middle of the night to eat a sandwich. The bathroom was not stocked well with paper towels, so there was no way to dry my hands after washing them. I also don't know how to order gluten-free meals before the flight."
Cons: "Horrible airline. But I knew that. Didn’t have much choice on short notice. I avoid this airline as much as humanly possible."
Pros: "Nothing."
Cons: "At least they didn't try to sell us again on the credit card."
Pros: "The low initial ticket price"
Cons: "Having to pay for a seat and baggage after buying a ticket. I got an earlier standby Delta flight on Friday so I skipped the first Spirit flight (which ended up being delayed anyway). On my flight back to Denver today, I found out in the terminal that my entire trip was cancelled because I missed my original outgoing flight. I was never notified of this cancellation through email or phone call. I was then asked to pay another $200 for a one way ticket back to Denver. Luckily I was able to fly standby on Delta again instead. Never flying Spirit again. Terrible customer service as well."
Pros: "Nothing. I was treated so poorly I walked away from their customer service and bought a ticket on another airline."
Cons: "I was 5 minutes late over their 45 minute required check in window. So they cancelled my ticket. For $100 they offered to reschedule me. And for another $50 they would check my bag. On a different airline I paid another $100 and got a complete round trip ticket, about 10 minutes later."
Pros: "Nothing"
Cons: "I arrived at the terminal three hours early, connecting from a non-Spirit flight from Central America. Spirit employees wouldn't check me in, saying they were too busy and I need to wait, but no worry, there's plenty of time. Asked again later and was told to check in online. Checked in online and was told (after the many upsell screens) that I couldn't print a boarding pass and needed to go to a Spirit counter. Went back to the Spirit gate and they said I hadn't checked in so they gave away my seat, and they didn't have another flight until tomorrow. Did I want it? Nope. Bought tickets on a real airline. Will never, ever travel with Spirit again."
Cons: "The seats are cramped and on the way back, they canceled all flights back to Houston, causing us to pay an extra $600 in order to get home to work on Monday."
Pros: "Absolutely ridiculous policy on making me go to a different terminal to get a boarding pass. Every other airline in the United States can issues electronic boarding passes these guys blocked me out 1 hour and ten minutes before the flight and said I had to go to terminal E counter to get boarding pass. I was at terminal A. Because I did not have boarding pass I could not enter through terminal A and use skylink I had to take the bus instead. That took 25 minutes. Then when I arrived at counter they said the flight was closed. And even though it was 25 minutes before boarding I was out of luck. The rude counter person said I should have been there 3 hours before the flight and now all they can do is reschedule for another day and it will cost an additional $100. Fortunately there were about 10 other people in a similar situation as mine and it became overwhelming for the counter people and they started issuing us tickets. This caused 10 of use to rush to security yelling we only have 10 minutes to get to flight. Fortunately all the people in line were understanding and TSA did the best they could but it still took time and probably stressed everyone out at security including TSA. This was just a money grab by Spirit airlines. Any other airlines an electronic ticket would have issued to my phone and I could have entered security at terminal A, caught skylink to Terminal E for my flight and been at gate 30 minutes before departure. This ridiculous policy of locking me out over an hour before the flight caused a great deal of stress to myself, the spirit counter crew, the TSA, all the other airline passengers waiting at security, and all the other spirit passengers who were gamed by Spirit airlines moneygrab. I intend to file complaints with Better Business Bureau, FAA, and Homeland security. This was totally unnecessary chaos!!!!"
