Airline reviews
Pros: "The crew was supportive."
Cons: "Not being on the tarmac for nearly 3 hours due to a "warning light" could have been better."
Pros: "The crew was supportive."
Cons: "Not being on the tarmac for nearly 3 hours due to a "warning light" could have been better."
Pros: "All middle seats blocked and unoccupied until September 30th... made for a very comfy flight. Very clean airplane made me feel safe."
Cons: "USB power ports would be nice"
Pros: "The crew was amazing"
Cons: "It was so stuffy and hot in the plane. I could not breath espacially because I was pregnant."
Pros: "The Southwest cress are always so nice. I love the free checked bags!"
Cons: "Southwest is getting a little pricey, maybe that comes with success - the old "supply and demand" thing... Also because it's so popular, the flights are often full and the seating plan (or lack there of) really puts me off even if I end up with a decent seat."
Cons: "Food is not expected but stale pretzels are worse than nothing. No entertainment"
Pros: "Departed on time and arrived 10 minutes earlier than scheduled. Took advantage of early check in and that was good."
Cons: "Wish it was more than cookies or pretzels that they serve."
Pros: "Southwest is my go to airline. No nonsense. Not nickel and diming me for every little thing like the other airlines we have all learned to loathe."
Cons: "The flights are packed. Frequently late."
Cons: "Plane ac was not working... seats extremely thin hard for little by rides"
Pros: "On-time departure and 15 minutes early getting into Denver’s DIA airport. Very clean and well-maintained aircraft. Funny crew was like a convention of standup comedians yet totally professional. I’m looking forward to my next Southwest flight."
Pros: "Crew made certain that flight would not be delayed. Heavy winds as we got close to Ontario Airport, but pilot made great landing!"

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."
Cons: "Flight on time and not wait 30 min on the runway to get to a gate once landed"
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: "Timing of the flight was always good. Efficient flying. Crew was super helpful too even when passengers were a bit too much."
Pros: "The seat was nice."
Cons: "Offered water or Orange juice in a can due to a short flight. I may recommend no canned orange juice, due to the quality ingredients and something more freshly squeezed for health benefits. And offers coffee or tea."
Pros: "It was a quiet early morning flight that went smoothly."
Cons: "There could have been more leg room provided for the aisle seat passenger."
Pros: "Crew were very attentive and hospitable to the crew. I have been flying ASIANA many times and enjoy the flight as well."
Cons: "Great flight and their service was great. Looking forward to my next flight with them."

The staff was very professional, the places very clean. The legroom was a little bit tight but so worth the price of the flight. Very pleased! Next time, I want to book a stayover to explore Iceland :)

The boarding process was easy, the crew was friendly and the flight was very smooth. There is a limited menu the food was tasty, but you have to purchase everything. The cost of the flight was very reasonable but everything such as baggage is extra.

Play is a great budget airline. There are no TVs or chargers in the seat but there was more legroom than expected. Boarding and all staff that I interacted with were great. You have to pay for any and all drinks or snacks you might want on flight.

Play is a great budget airline. There’s more legroom than expected, no TVs or chargers in the seat, all staff that I interacted with were great.

Blood sucker budgeted airline. Charging after and after. No one should busy air ticket in this airline. Completely a scam and sucking blood.

The cabin crew very kindly arranged a change of seats for us due to a distressed passenger

There was no food or entertainment. That was fine, not a problem. I paid for “priority boarding” ( and a cabin bag) but there was no “priority boarding.” That was disappointing and falsely advertised so perhaps that could be adjusted.

No frills airline. Excellent service. Very good leg room for passengers compared to other "full service" airlines. Crew was very friendly. No entertainment system other than flight information display which was surprising as I thought it would be another revenue stream for them. Overall a surprisingly excellent experience.

Great new carrier to Europe. Lots of leg space and friendly crew

Worst seating -- by several orders of magnitude -- on any aircraft in sixty years of flying regular and budget airlines. The seats are cramped from side to side, barely padded, short from back to front. Tightness was at first absurd and then actually painful for a five-to-six hour flight. Pitch between rows is so small that even turning to stand up to get into the aisle is difficult. And I'm a slender guy, 5'9", 170 lbs. Website for booking held many "mysteries" like hidden access to payment portal. Though one screen said my booking and payment were complete, I learned at the airport that "complete" was not true. Had to work with helpful supervisor at the check-in desk Online I was able to change my flight booking from Saturday to Friday, But also I learned at the airport (too late) that the carry-on bag fee from the Saturday flight did not automatically shift onto the Friday flight. I had to pay the much higher at-the-airport charge, 49 euros. I will try to get an adjustment.

Cons: "Made us check our carry ons and there was plenty of space in the cabin overhead comoartments"
Pros: "The crew was very attentive and had great personality. They anticipated any needs we had."
Pros: "Good seats"
Cons: "Flight was delayed and my luggage didn’t make the plane."
Pros: "Service was great."
Cons: "It was a shortest duration flight of the three so I couldn’t point out here what was lacking. Thank you!"
Cons: "Left seven hours later than I anticipated Some passengers were rebooked on earlier flights while others told to go with same flight flying later Very very disorganized"
Cons: "Flight attendant in First class was visibly frustrated and unfriendly. He was not helping with my simple request for a blanket. Also, the were no food service in first class."
Pros: "The crew was super friendly and professional. Enjoyed the reworked safety message before take-off."
Cons: "The Comfort+ seat, while it had plenty of leg room in front, had a small width-box that many Americans (being larger than perhaps they should be) will find extremely uncomfortable at best, and unable to fit in at worst."
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: "Just a great experience Delta is still above the rest excluding Hawaiian"
Cons: "Cant think of anything"
Pros: "The plane and entertainment system was good. The cabin crew was a little slow. But all in all it was a good flight."
Cons: "everything sucked time bery bad servive starfed on flight nonacolok was sergvedngypu ilt was really disappoinyling includigbymkthrvlounhr aothee airlione"
Pros: "Specially food service and also boarding"
Cons: "They checked carry on again even you passed from the counter I felt very bad about this"
Pros: "Flight time and layover at connecting flight"
Cons: "Food needs to improved. In all other flight Indian spice is served as Asian veg flight seat are too tight"
Pros: "Professional and friendly staff. Excellent film selection."
Cons: "Not enough security staff at Istanbuñ and no one from the airline to assist. The queues were too long at security so I had to run to make my flight. Lots of other people had the same trouble and I believe my cousin missed her connection."
Pros: "The food and entertainment were okay."
Cons: "The staff was rude. The entertainment consoles didn’t work well."
Cons: "They are telling me because I booked with Kayak through PriceLine or vice versa they will not give me any hotel for my 14 hours lay over."
Pros: "I liked the food and the staff were very friendly"
Pros: "The entertainment was excellent!"
Cons: "The comfort level for that long of a flight was very poor. Seats are way too close together. There is no knee room from the seats at the front at all. People operating their video monitor is a disturbing fact for the passengers who sits in front of them."
Cons: "Service on this flight was significantly better than the Cairo flight, probably just because this flight goes to London. Welcome drink were promptly served but the food choice was still a big no-no. EVERYTHING CONSISTS OF DAIRY PRODUCT THAT I M ALLERGIC TO. When I brought this to the flight attendant's attention, none of them was apologetic and none of them tried to find out another solution to me, who was flying their airline the first time and didn't know the not-so-diverse food option."
Cons: "car seat not wrapped in plastic bag so I lost my cushions on the seat. Now my child can no longer use it."
