Swiss International Air Lines review by Martin

I suppose to travel from Zurich to Hong Kong with my wife and my 90 year old auntie. Me and my auntie had a business class ticket because of her health and my wife a eco class ticket. Totally we paid 9500 Euro for those tickets. Unfortunately my auntie couldn't go back to Hong Kong as her health condition changed in the last minute before go to airport. I asked ar the check-in if my wife can take her seat instead, the answer was: yes, if I pay 1500€ for upgrad. I denied and they immediately annulled the ticket of my auntie and sell it to another passenger. I WILL NEVER EVER FLY SWISS AIRLINE AGAIN!! I hope I can reach a few people and warn them from this s*** airline. Regards Martin
