What would happen if I tried to check in with a rtw ticket at lhr (ba) that was supposed to be a transit originally but decided to take a flight the next day thereby making it a stopover - would they demand fuel surcharges/fees etc and a ticket reissue ($150?) or likely not to notice?


On a seperate question what is the best route to maximize F routes in Asia while also maximizing destinations, right now I have
HKG-NRT-TPE-ICN-HKG - all of which being F except TPE-ICN. Is there a different configeration of Asian cities that would also get this number of F routes? I wanted to get BKK in (instead of TPE or ICN) but it didn't seem to work out.
