Just to add….just tried a quick dummy booking on ba.com for LHR-ASQ and it does not come up as an option. Hopefully it’s just a system thing and not that Austin, Nv is a destination uncovered by the JSA (meaning your son would have had to purchase a separate ticket with AA MIA-ASQ).If this is the case unfortunately he will fall prey to AA’s rules when it comes to policies on accommodation.
Actually lloydah looking at AA.com they do not sell MIA – ASQ or Austin. Nv either. It was definitely Austin Nevada and not Austin Tx he was flying to?
