This is actually a problem for me. I am 6'8" and booked LHR-SJC in June in World Traveller. I purchased exit row seats for three of us on the 787, now there are no exit rows in Y on this aircraft. Called and asked to be put on A380 to SFO instead, was told no since different city but they will be kind and offer me a refund of the seat purchase. Do you think I could convince them to change routing (via LAX) as long as my destination is still SJC? If not, best contingency if I have no choice but to stay on the 747 to SJC?
