Flying business class but the experience was that of economy class

Boarding was very slow and unorganized. As a result we were delayed for 25 minutes crew is not friendly. food , entertainment and service was mediocre I bought in flight internet and paid $42.61 it did not eben worked after 10 minutes and no one helped I would like a refund on that please

Flight was on time. Food was ok. Entertainment non existent.

Excellent excellent flight! I’m sure it helped that the turbulence and the weather cooperated, but the staff was wonderful. The legroom was perfect and my husband is 6‘1“ and he felt perfectly fine. Best flight I’ve taken in a long time.

The transfer was awful, everyone was running to catch the flight, there was no information on the process. We git to the gate and the boarding was late and had to stay in different lines but there was no guidance. The flight was late and uncomfortable, probably one of the worst flights I have been on. The luggage was sent to a different terminal and still did not make back to us.

The awful part was the customs delays at ZRH. The good part is the flight was delayed long enough to accommodate. The flight itself was fairly comfortable.

It was on time and we arrived safely—that's a good thing. Other than that, my son's seatback storage pocket was ripped and couldn't hold anything, and his footrest was stuck so he couldn't use it. You pay extra money for allegedly more comfort, but the plane was old and the seats were broken. No drinks were offered in the beginning like in other premium economy settings, no hot towels. It was really basic and nothing more than economy other than three times the price. Very disapointed. My food tray was VERY dirty—I couldn't even eat anything after seeing that. I will try to avoid SWISS in my future travels

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.
