Terminal Navigation
IAH spans five terminals (A through E) connected by an underground train, with most international business class departures operating out of Terminal D, which houses dedicated premium check-in desks for British Airways, Air France, and other international carriers. American Airlines business class check-in operates from Terminal A and B, so confirming your terminal before arrival saves significant walking time.
Ground Transport
Taxis and rideshares from IAH to downtown Houston run approximately 25 to 35 minutes and cost between $55 and $75, making them the most practical option since Houston lacks a direct rail link to the airport.
"Business class travelers departing from Terminal D should clear international security using the dedicated premium lane on the upper level, then proceed directly to the Air France or British Airways lounge before the gates open, as the Terminal D lounge corridor fills quickly during the evening European departure bank."
