The biggest let down was with booking experience through Kayak. I booked a flight with checked bags on Kayak. Right away I got a message from travel agency that the flight is not confirmed and to call them. I called them and they said the flight I have booked is no longer available with the price I have booked it for and I can book it with about $100 more. I already had other options I could book with cheaper price so I asked them to cancel my booking. Then they said I can have the ticket with the same price but a date change which was not working for me as I had to be there for a seminar. So again I said no then they said they will cover the charges and confirm my flight. When comes time for check-in I see I have no checked bag option which means the travel agency deceived me saying I can have my booking as I had booked it. And at that point I ended up paying $155 for my checked bag going back and forth. I am extremely angry and unhappy with this experience

PLEASE DONT TAKE FORCEFULLY(SIZE APPROPRIATE) CARRY ONS FROM PASSENGERS WHO FOR SOME REASON NEED TO KEEP IT

It was great. My seat was comfortable. The bathrooms were clean . The service was superb . I travel a lot and I have been in 64 counties. I wish I could fly first class, even though I could , but I prefer to budget my yearly travelling expense on actual visiting , not on flight. Anyway, my point is that your economy was far much better than other airlines as good as Air France. The flight attendants and all crew were polite and very helpful and respectful. Thank you for making my long trip tolerable.

The service was flawless. The trip went great. I flew from Venice, Italy to Tampa, Florida. The issue is my bag (that I checked for free when checking into the flight) was ripped along the side when I collected it from baggage claim in Tampa, last night. I thought of talking with the Tampa baggage claim employees about it and see what could be done, but my bag isn’t a very expensive bag and I didn’t want to make a big deal of it. I’m not sure if I’ll be checking a bag anymore in the future.

My luggage did not make the connection and 4 days later I still have not received it.

We're talking about a short-haul in-country flight.. there is no confort, no food, just the bottle of water. The seats are squeezed like hell and I was in the back-end of the plane, with one spare row left for the crew and to store excess bags that could not fit in the overhead bin.. Speaking of carry-on, some passengers should be better screened as their bags were simply too big to fit in the overhead bins.. ! How can this happen, and it was an A310, with 2 columns of 3-seater rows.. There is a pseudo-Business class, which is simply a section in the front of the plane where the same seats are occupied only 2 out of 3, on each side, leaving more rooms for the passengers and their bags. That's it.

We are flying with Swiss for a long time but this time was terrible do to are flight cancellations we are in some bad hotel with out normal food

It is a good airlines, very professional very good food. I wish they offered free luggage is the only thing.

I like how professional, fast and good the whole experience was.

Nothing special.. they could have provided something to eat without a charge

Service was very good. Because I use a cane, I was allowed to use Priority Boarding. Biggest problem was extremely limited leg room in Economy class seats. For airplane food, it was alright.

Was late but that airport/storm fault. Flight was full but comfortable. Food quite nice. Unfortunate that I had a rather miserable attendant, others were much friendlier

Experience was good. Could have been better if we didn’t have to board an hour before the flight to ghana and miss relaxing time in the lounge. That process was very stressful

Boarding crew is unfriendly as i was asked to handover carryon luggage too upto final destination Bangalore I was not prepared for that and i had to travel without my diabetic and hypertension medicines

I was charged fees for check in bags at the airport by British Airways. It was supposed to be no charge but Kayak messed up my booking apparently and I had to pay for check in bags. I paid $175.

They took my carry on and checked it in. Staff in general at Heathrow are not friendly or helpful

The crew were professional and friendly. It was the most uncomfortable international flight I've ever flown. Crammed in passengers. No overhead space to put my bag. No leg room and unable to recline seat due to seats too close together so it upset passenger behind me! Upgrade price to get 2 inches of more space unreasonable.

Boarding in Dallas was hell with extremely rude gate agents , especially a lady named Rajathi who was the epitome of rudeness with no compassion at all . She was horrible and I wonder why airlines have people like her on their roster who exude arrogance and haughtiness . Will probably not fly British Airwsys because of people like her .

Less than average, low level of shared required information needed during the transfer from airport to another, also the used team during boarding In Indianapolis station is Not Professional

Food was average. Better headphones seats were average at best.
