Ground staff in BKK said go away and buy a ticket from another airline. Don't discuss with me, we send away 10+ people every day because of this. We (4 people) got rejected from boarding our Vietnam Airlines flight VN6800 because of operational problems. That's not an issue as long as you get offered another solution. We were sent away impolitely with the words above. We had to buy 4 new (expensive) tickets from other airlines.
