Whether you’re a first-time traveler or a frequent flyer, understanding the layout, facilities, and procedures at IAH’s British Airways terminal can help your trip start stress-free. In this guide, we’ll cover everything from check-in and security to dining, lounges, and tips for a smooth departure.


British Airways in Terminal D

Location & Access

Terminal D is dedicated to international operations for many non-U.S. airlines. It is designed for efficient passenger flow, with ticketing on the upper level, baggage claim on the lower level, and security leading directly to departure gates.

British Airways flights to London Heathrow depart exclusively from this terminal. Renovation projects at IAH are modernizing Terminal D, so depending on your travel date, you may notice upgraded waiting areas, new dining spots, and refreshed gate spaces.

Check-In Process

When and How to Check In

British Airways offers several ways to complete the check-in process:

  • Online or Mobile App: Opens 24 hours before departure; allows you to choose seats and obtain a mobile boarding pass.

  • Airport Kiosks: Self-service stations in Terminal D’s departure hall for printing boarding passes and tagging luggage.

  • Check-In Counters: Staffed by BA agents for passengers with special requests, extra baggage, or ticketing changes.

For international flights like Houston to London, it’s wise to arrive at least three hours before departure. This ensures you have enough time for check-in, baggage drop, security, and possible customs processing.

Baggage Guidelines

British Airways includes a baggage allowance in most long-haul fares, but details vary by class of service.

General guidelines:

  • Economy (World Traveller): 1 checked bag up to 23 kg (50 lbs)

  • Premium Economy (World Traveller Plus): 2 checked bags up to 23 kg each

  • Business (Club World) & First: 2 checked bags up to 32 kg (70 lbs) each

  • Carry-On: 1 cabin bag plus 1 personal item allowed in all cabins

If you have sports equipment, musical instruments, or oversized luggage, check BA’s special baggage rules ahead of time to avoid surprises.

Security & Departure Procedures

TSA Screening

After check-in, passengers proceed through the Terminal D security checkpoint. Because this area serves multiple international carriers, lines can be long during peak hours (afternoons and evenings). If you’re enrolled in TSA PreCheck, you may be able to use the expedited lane.

Boarding the Aircraft

British Airways uses a group boarding method:

  • Group 1: First Class, Club World, and elite Oneworld frequent flyers

  • Group 2–3: Premium Economy and other elite members

  • Group 4–9: Economy passengers, with later groups boarding last

Boarding typically starts 45–50 minutes before departure for long-haul flights.

Dining & Shopping in Terminal D

Even though Terminal D is smaller than domestic terminals, it still offers a variety of pre-flight options.

Dining:

  • Full-Service Restaurants: American-style grills, Tex-Mex favorites, and international cuisines.

  • Quick-Service Counters: Sandwiches, salads, and wraps for a faster meal.

  • Coffee & Snacks: Cafés and bakeries for drinks, pastries, and grab-and-go items.
