Thank you so much for reply, the departing flight from Heathrow is certainly more than 5 hours late of taking off, we are in standard economy so it's going to be pot luck on where we will be seated, I have been looking on expertflyer but it won't give me the seat map. Regards Taxi, my wife has been in touch with the taxi company and rearranged the times. . I doubt that I will have much choice of where we sit on Thai Air, they are normally busy flights . If anyone could check for me please. Meanwhile we can stay in the hotel room til 12
