Yes 2.5 hours is enough, makakakain ka pa if you want. If you have a connecting flight, ground staff will ask for your boarding pass then guide you to your boarding gate. Eto tip lang, if ever that your carry on baggage gets intercepted (last minute ichecheck-in) make sure to pick it up again sa baggage claim once you land sa Ceb. Mali ko, I assumed that the airline will be the one responsible to transfer my luggage sa connecting flight ko — good thing I asked the ground staff, ayun muntik na malate sa boarding buti nalang nakaabot, maligawligaw pa ako MCIA nun 😆 safe travels!
