A little delayed and the timing between flights was tight

A little delayed and the timing between flights was tight

the food was not good and was such a little amount, also the flight doesnt offer any free snacks at the back of the plane in case any passenger gets hungry. So many other airlines likes klm, air france always offer snack at the back of the plane. A lot of the passenger were complaining during the flight about that the they were hungry even after the meals were served. The variety of movies offer on the individual screens are really not that much, so makes the flight longer and boring

I have no Comment. Super clean, Fantastic Crew, Food was delicious. Also wanted to add the Zurich Airport. Super nice people everything is in order super clean.

I like it very much it was a good experience with an excellent service

The crew and service was excellent. The food and entertainment were very good but not excellent.

Swiss messed up a Geneva-Zurich flight on a day with perfect weather. Then they didn’t even let people with almost no time to catch connections disembark first. Finally, luggage missed the connection of course and it took almost 24 hours for it to be delivered. We lost a whole day of vacation stuck in the hotel waiting for it.

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

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.
