Do not get mislead by low cost business class tickets from some airline companies.
I recently bought a Business class ticket with Austrian Airline that was only few Euro cheaper from other companies.
For a crowded situation at the check-in, they closed the check-in while I was in the queue and they gave my seat to someone else.
When I went to the ticket counter to booked me in another flight, they asked me 4000 Euro more for flying in economy class, and they refuse to refund my ticket.
I had to purchase another ticket from another company.
Check the refund flight condition before you buy a business class tickets, apparently not all the companies has the same policies.
How can I get my money back?
