I seem to remember reading somewhere else that QF have said if LHR runs out of suitable capacity they will simply increase flights from FRA and feed UK pax through there. This despite both MAN and BHX being available!! Good luck PK and team, I think you will need it!
Indeed, if airlines are going to choose another country before trying out LGW or MAN then what chance does BHX have? Interesting though as I thought QF were on the verge of pulling out of FRA not so long back?
