If check in is being done online you don't have to waste your time at the airport and you can start right hereSelect your seat, choose and pay for seats with extra leg room - if available, pay for your baggage - if such charges apply and receive your boarding pass already at home or at the office. If you travel with more than hand luggage you can just drop your bags at special counters which are only available for passengers with a boarding pass.Time is priceless and this is the best solution to avoid long queues at the counters. This procedure is easy as many carriers now have introduced web service which is always available from 24 hours before departure and sometimes even earlier. Low cost carriers may require that passengers must use this service online and impose additional charges for those who not only drop their baggage at the airport but require check-in service or who may need a reprint of the boarding pass. Ask your travel agent when you make the reservation and/or get your ticket.
