I'm connecting from a BA (LHR - first class) flight onto an AA (to DFW economy) flight at Houston IAH in May 2024, a 2.5-hour layover - both booked on the same itinerary with AA awards.
I'm wondering what lounges I might have access to and opinions as to which might be the best option (if I have any choices

?
Thanks in advance for opinions and insights - Rob.
