Yes, you can generally get a boarding pass online for international flights, but there is often a "catch" regarding document verification. Most airlines allow you to check in via their app or website 24 to 48 hours before departure. However, for international routes, many carriers will issue a "check-in confirmation" or a "provisional boarding pass" instead of the final version. This is because airline staff are legally required to physically verify your passport and visa (if required) before you can board. In many cases, you can scan your passport using the airline's app to speed this up, but you may still need to stop at a "document check" counter at the airport to get your final, valid boarding pass. Once verified, you can use a mobile boarding pass at most modern airports, though some countries still require a printed paper copy for immigration records. Always check the specific "ready to fly" requirements for your destination in the airline's app.
