Hello everyone I am a traveller and do you know — How Early Can You Check-in for British Airways? Online check-in is available through the website or mobile app, allowing you to print or download your boarding pass. If you prefer checking in at the airport, help desks open around 2-3 hours before flight time. It's important to arrive early, especially for international flights, as check-in typically closes 60 minutes before departure. This flexibility makes the travel experience smoother and more convenient for passengers.
