Prior to COVID, IAH had 777 flying to LHR (1 or 2 depending on season), FRA , AMS, NRT, EZE, and HNL. The 787 did SYD and either a domestic 2 day or one of the LHR’s. The 767-300 covered MUC, GIG, GRU, LIM, and SCL. How things shake out after this is anyone’s guess. Junior pilots will most likely have a crack at the 777 while the senior ones ride out training freezes as NB captains or simply wait until things settle down before bidding back. If awarded a junior slot on the 777, expect to be junior for a really long time while more senior people bid on top of you. Buyer beware.
