Long time lurker, first post - be gentle.

I got a Y award booked through AE a few months back.

outbound YVR-YYZ-GRU (AC, in Feb - just in time for carnival)
and
inbound UIO-IAH-ORD-YVR (on CO) for June 5th.

When I booked it, I only randomly picked a return date fully knowing I would change it to 1st/2nd week of August eventually.

Checking on KVS, and having now just talked to AE it seems there is no availability for UIO-IAH for the whole month of July and August in Y.

Has anyone experience with this? Is UA/CO releasing inventory closer to the date or am I out of luck?

I would not think July/August is peak travel season to/from Ecuador...

Worst case I suppose would be AC back out of BOG, but I'd rather safe some fuel surcharges.

Appreciate any help and tips
