I think the more likely international destinations that might be added in the next few years would be along the lines of MDE
and CLO in Colombia and a return of GYE
in Ecuador. Those are all reachable by narrow-body equipment.
That said, I think that the US-Colombia market is heavily skewed towards the East Coast. However, UA
might be able to pick up enough California-bound passengers with a connection at IAH
that they could make a 73G or A319 work.
Of the European destinations mentioned, the only ones I could envision would be OSL
, and both of those are rather big longshots. I don't think Repsol generates enough MAD
traffic to justify a flight, in the same way that Eni doesn't justify a n/s service to FCO
, and previously CO
just plain waited too long to jump on the Middle East bandwagon out of Houston. QR
, along with TK
, really have that marketplace covered for now. The only way UA
keeps their routes to the Gulf out of IAD
is by having the benefit of having Pentagon officials needing to buy American first when purchasing tickets.
