When you arrive at the airport, check-in can be made more streamlined by opting for online check-in, usually available 24 to 48 hours before your flight. This not only saves time but also allows you to choose your seats in advance. Stick to your travel essentials, ensuring your bag complies with the airline’s luggage guidelines to avoid extra charges. It’s wise to pack light while still having all necessary items; this will simplify the process and can save costs associated with checked baggage.
