Airline reviews
Pros: "The crew was very friendly. The seats were comfortable. But most of all, I felt safe on the flight."
Cons: "Nothing I can think of. Thank you for a peaceful flight."
Pros: "The crew was very friendly. The seats were comfortable. But most of all, I felt safe on the flight."
Cons: "Nothing I can think of. Thank you for a peaceful flight."
Pros: "Seat comfort. Seats are really roomy."
Cons: "The landing was impactful; we literally hit the ground. Landing could have been smoother. We sat between runways for 15 minutes. Not good."
Pros: "Food was excellent service was good"
Cons: "Boarding was too slow we sat at gate for almost an hour for baggage to be loaded"
Pros: "Great crew, smooth landing."
Cons: "The “Mediterranean tapas” meal is basically a tiny tiny school lunch, minus the comfort of PB&J. Want dried apricots? You get FOUR. All in all not too bad though. The entertainment/WiFi system is limiting- maybe REMIND us to bring headphones? And no WiFi unless you have T-Mobile? Tease."
Pros: "Clean, newer plane on time with courteous professional staff. All went very well."
Cons: "Not a thing."
Pros: "The crew was so darn efficient and the pilot was so funny over the speaker! Thank you Alaska for slaying this flight"
Pros: "Employees were friendly and helpful"
Cons: "Every single flight left extremely late which meant I was running through the airport to catch my connections."
Cons: "We had to go back to the gate after we started the taxi to take off because some idiot had remembered he left a lithium battery in his checked luggage... The service cart kept hitting me and the attendant didn’t even say sorry or excuse me... aisles are too narrow... seats are too small. The guy next to me wouldn’t put the arm rest down because he felt to cramped, so he was hitting me with his elbow all evening... I’m just not happy, but glad to be home."
Pros: "Flight was on time-ish, no trouble really. Call center folks were great."
Cons: "Our original flight was cancelled with no explanation. My girlfriend was notified of this and I was not. When I called to get my flight details I was informed that I was to fly out on a completely different day instead. After explaining that there was no chance of that happening, the call center rep was happy to help. The flight was now an American Airlines flight booked through Alaska. About 3 days before our flight we both received calls from American saying that they did not have our passenger information. Apparently Alaska just didn't transfer that over. We also now had two confirmation codes as the returning and connecting flights were still with Alaska. Once we got to the airport on the day of I was able to print my American Airlines boarding pass, however I could not print my Alaska boarding pass on neither American nor Alaska's kiosks. It was a redeye flight as well so there was no staff at the check in counters yet. We ultimately did get to our destination, but it was such a completely unnecessary headache to get there."
Pros: "Comfortable seating but I paid for it"
Cons: "Flight attendants seemed bogged down. The one from first class came into premium seating to help some people"
Cons: "This plane was too full for social distancing. I was really skeptical about this flight as it relates to the COVID pandemic."

Pros: "The crew’s positive energy and great service were truly amazing. Kudos Delta!"

Cons: "Smallest seats I’ve ever been in. Late departure because they forgot the plane’s security check in-between flights. Drinks served but no snacks."
Pros: "When I checked in for my flight I was given another passenger’s ticket (very similar name) and my checked bag was then sent to this other flight destination. when I got to my gate (correct destination) I discovered the error. The gate crew worked hard to get my checked bag off the wrong flight and rerouted to my flight within 20 minutes of my flight’s departure."
Pros: "it was a direct flight"
Cons: "allowing to check bags in late. didn’t allow us to & made us take our bags thru TSA.

They said “it’s okay, just let tsa know we said it was ok” tsa threw our stuff away & lost a lot of"

Cons: "They could’ve let us check our bags to make our flight on time."
Pros: "The seats are not comfortable at all. The tickets that we bought promised a USB port and there were none. And oddly enough, everything around me was very sticky. The seat, the seat in front of me, the window.. it was an overall uncomfortable flight"
Cons: "At least one USB port per seat would’ve been nice. The WiFi was so slow that I couldn’t even send an email. And maybe the seats could’ve been wiped down a bit."
Cons: "Terrible logistics. Stuck on tarmac because they couldn’t clear the previous plane out of the gate. Fellow passengers missed their connecting flights."
Pros: "Flight was not over crowded, allowing for proper social distancing! That is MUCH appreciated. Crew was wonderful."
Cons: "The couple in front of me got in a physical altercation as well as the couple seated behind me. Both situations caused much discomfort and could have been defused faster by flight crew"

Cons: "Cramped seating in basic economy, the upgrade seating wasn’t much better"
Pros: "I didn’t die."
Cons: "I researched United’s, FAA, and my car seat company website before trying to board with it. I was told by flight attendant that I could only bring the car seat on board if it had a sticker? I don’t know what sticker she was referring to and it’s tough to keep a toddler safe with just a lap belt"

Pros: "Flight was on time. Friendly crew."
Cons: "It turned out that we were on stand by (without anyone telling us until the morning of the flight) and did not know if we were going to fly out. We could not select any seats at check in and only found out our seats a few hours before the flight. It was quite unpleasant and stressful as my husband and I were flying with our two children and faced a real possibility of not being able to sit together or getting bumped off a flight all together. It was a code shared flight between Lufthansa and United and each airline kept sending us to the other to get any answers or help. neither were helpful. It made it for an extremely frustrating experience."
