On checking in for a flightWeb check–in.
Self check–in kiosks.Use it.
When web check–in is offered, use it. If the traffic is bad on your way to the airport, you don't have to worry about making it before the check–in counter closes... you only have to worry about making it for boarding.
When web check–in is offered but you have no access to the internet, worry about making it to the airport before check in closes. If you find yourself at the end of a mile long queue for the check–in counter, propel yourself toward the self check–in kiosks (which, in the Philippines, is usually devoid of any queues).
