For a domestic flight, passengers are asked to do check-in within 1 hour before the departure and 2 hours before the departure of an international flight. The check-in departments also close 60 minutes before the domestic flight’s take-off and 75 minutes before the departure for international flights. If the baggage weight detects higher than the allowed weight, then you’ll be charged extra.
