On time arrivals and departure, good in flight entertainment, courteous flight attendants, decent meals, reasonable seat space

Close was excellent. Comfort was very good. The food was marginal.

Didn't make the connection as my primary flight was 3 hrs late, I had to basically beg to be put on a different airline to continue my trip otherwise I would have been sitting on the airport for 8 hrs

Best service we’ve ever experienced! Special thanks to the crew member who took care of us throughout the journey. It was truly a once-in-a-lifetime experience. We love Swiss Air!

The boarding of this flight was total chaos. For some reason, all passengers had to stand in a lengthy line at the gate to have our passports checked for the FOURTH time. No reason was offered for the necessity of the fourth re-check, and when we got to the end of the line, the check was perfunctory. There was little to no crowd control at the gate and in some cases, tempers were flaring. On the other hand, once we got on board, everything about this flight from start to finish, especially the quality of the food and the service, was probably the best I have ever experienced..

Boarding was very chaotic, we had to stand in two different lines that were not clearly marked, and the announcements were not understandable from the microphones, and we speak both German and English. We paid Kayak $120+ for seat assignments when we purchased our tickets but when we printed our boarding passes, suddenly we had been changed to 16 rows further back than our assigned seats we paid for. The seats we were assigned to on our boarding passes had no usable overhead bins and so we had to sit with our carry on backpacks underneath our feet in an already crowded space. One video/entertainment screen kept crashing and thus was useless for viewing anything. It was not an enjoyable flight.

The biggest plus point of this flight is that the crew was very friendly. Otherwise on European sectors, the Business class seats are a joke and there is no entertainment of any kind. The staff should be trained to greet the Star Alliance Gold members to make them feel special.

Everything was fairly easy just hard when you get to Heathrow not know your Gate number until an hour before but otherwise really everything great. Did not get my texts in time though to do me any good but that is why I still like everything the old fashioned way and print everything out.

I have no complaints. The crew was attentive, pleasant and heloful

Missed connecting train since flight was late into Zurich and I had to stay at airport hotel because of it as well as I had to repurchase train ticket

The flight went well. However the leg room in coach class is very very tight. We arrived early but could not get to the gate early….sadly. Also something about off loading cargo- we had to wait to deplane. There was not clear explanation for that.

Good shuttle to Europe. Face check boarding needs overhaul. 2 stations for 200 people and still with passport check. Why have both? Why is this now slower than 5 years ago?

I was a bit disappointed that checked in luggage was not included in the ticket. That should be a standard thing for most international flights.

Worst travel experience ever. One flight missed due to a delay, got rebooked, that one got cancelled and 0 customer service whatsoever. No help for finding our luggage or getting a hotel.

Easy quick flight but everything was perfect. I never like the food and it was surprising good this time. I think they are making some changes.

On board was excellent—a remarkable positive change. Check in was horrifying. Forced to check in branded cabin baggage approved bags weighing 10 and 12 kgs each, because desk insisted these were not fit for overhead lockers. Got charged £160 for two bags. Behaviour of staff was hostile, motivated and rude. Wonder if BA pays commissions on collection, or borrows staff from Airport operator. Basle evidently is an airport used by budget airline— and customers are treated like consumers.

the old seats really need to go. they are not comfortable and outdated by many years. I waited over 40 minutes for my bag, unacceptable!

Flights were in time, everything was organized, food was really good!

The flight was cancelled on the day of departure (do not know if it was my connecting flight from Geneva on British Airways, or the flight from London to Boston, as no explanation was provided). I was rerouted through Paris on Air France, and then the flight from Paris to Boston on Air France was cancelled due to aircraft problems. Terrible travel experience so far. Current routing takes me to Detroit on Air France, then to Boston on Delta. May never see my checked luggage again. We will see.

Plane delayed several times due to mechanical issues. Plane not very clean and crew not very friendly.
