The second tool, Sky Airline’s web check-in process, is an online system that enables passengers to check-in for their flights from the safety of their home or office. A boarding pass will be issued automatically once the passenger has completed the check-in process and can be printed, downloaded to a phone or apparatus, or sent via email. Web check-in is accessible up to 24 hours before a flight’s takeoff and closes 4 hours before takeoff . Passengers are advised to arrive at the airport at least two hours before the designated takeoff time to enable plenty of time to travel to the airport, check baggage, and pass through security.
