Hi

I will be flying business with Swiss to Bkk. It just happen that friend of mine is on the same flight. I was trying to get an upgrade to business for him but it was so far not cleared and now it looks like this flight does not have any availability in business anymore.

My friend has some pains in his back when seating for long time - nothing he can not handle. However I would like him very much to flight in business class if possible. I wonder if we could switch our places so he can fly in business and I would fly in economy. Could I simply ask at the gate or flight attendant for this switch?
