The cornerstone of the itinerary is 2 seats in J on LH440 A380 service from IAH to FRA. However, we ultimately want to end up at LHR for a few nights. It's an 18th birthday gift to my son...ok, and maybe a bit to myself, too
This was my initial routing, which backtracks, so is invalid:
SEA-IAH-FRA-LHR STOP LHR-FRA-SEA
The only idea I can come up with after spending wayyy too much time putting together dates and flights that work is to drop the FRA-LHR-FRA segments and buy a return ticket so I'm simply flying SEA-IAH-FRA STOP FRA-SEA.
If anyone has any better suggestions, I would greatly appreciate some input.
TIA.
