British Airways (BA) offers a "Twilight Bag Drop" service, but its availability is limited to specific airports and flight times. In 2026, this service is primarily available at London Heathrow (Terminal 3 and 5), London Gatwick, and Edinburgh Airport. It allows passengers with flights departing the following morning (typically before 10:00 AM) to drop off their checked luggage between 4:00 PM and 9:00 PM the evening before. This is an excellent way to save time on the morning of travel and skip the long bag-drop queues. To use this service, you must have already checked in online and you must bring your boarding pass and passport. Only one member of a traveling party needs to be present to drop off the bags for everyone on the same booking, provided they have all the necessary travel documents. This service is free of charge and is particularly popular for families or those staying at airport hotels. Always verify the current "Twilight" hours on the BA website before heading to the airport, as times can fluctuate based on seasonal schedules and terminal staffing levels.
