I had no problem to reach BA in Japan, but the only thing they could offer me was to re-book me on a later date (but just my flight to London not to STR -strange) so the other option was that she would send a fax to the airport office and I should be there asap tomorrow morning (the office opens at 7.30 am and the flight was supposed to leave at 10.55 am) - that will be a chaos for sure.
How big are my options to get re-book on a SAS, Austrlian Airline or Swiss flight that all do leave at the same time as my original BA flight? If the airports will be open of course!
