IIRC, the interviews previously reported quoate the chairman as stating the first flights would be domestic followed by LHR followed by FRA. Given this, the fact that FRA has been downgraded (capacity-wise) to a 77W this winter, and TGs greater need to retain custom from LHR then I believe LHR will get it ahead of FRA. I'm shortly going to be making my rservations for next December for EDI-FRA/LHR-BKK, not too sure what to do but currently leaning towards LHR but then the question becomes whether to opt for the day flight or the night flight. Might yet end all the uncertainty and take detour via SIN with SQ although I'm not too crazy about their seats.
