Certain airlines offer the option to check-in your luggage online from the comfort of your home or office, allowing you to print your boarding pass and select your seat. Web Check-in is available from 48 to 3 hours before your departure, according always to the policies of the particular airline.
By using the Web Check-in service you save time, which you can spend more pleasantly at the airport, as all you need to do is drop off your luggage (if any) at the Bag Drop-Off counter of your airline. Make sure you check your airline’s website well in advance.
