How early can you check bags for a flight?
  • To have plenty of time to drop your luggage, clear security and arrive at the correct boarding gate, get to the airport three hours before an international flight. For a domestic flight, show up around two hours before. Even if you've already selected your seat and downloaded your boarding pass at home, it's worth keeping in mind that there are closing times for luggage check-in. It's one hour before departure for international flights, and 45 minutes if you're traveling domestically. Of course, times can differ between airlines, so it pays to check these details well ahead of your flight.
