Business Class Flights from Houston

Houston Intercontinental is the energy industry's airport — a city where oil-and-gas corporate travel to London, Dubai, Lagos, and São Paulo drives steady premium-cabin demand year-round. United is the dominant carrier at IAH with Polaris service to London, Frankfurt, Tokyo, and Latin American destinations. Emirates operates the daily IAH-DXB non-stop that serves the entire Gulf energy corridor, and British Airways runs the IAH-LHR service that connects Houston's corporate base to the UK. Qatar Airways' IAH-DOH frequency adds QSuite access from Houston — genuinely one of the best business class products available from any Texas airport. The energy-industry demand pattern creates pricing quirks: Monday departures and Thursday returns spike because of offshore rotation schedules, and Tuesday/Wednesday departures can be $300-400 cheaper on the same route. Houston's Latin American network is also strong: United flies Polaris to São Paulo, Bogotá, and Mexico City, and LATAM codeshares add deeper South American coverage. IAH's Terminal D (international) has improved with the new United Polaris Lounge, though the walk from domestic terminals remains long — allow 25 minutes minimum for connections.
