Okay I purchased a round trip ticket from Los Angeles to Cebu, my return flight is 90 days later. I'm flying on EVA AIRLINES. My intent is to go to BI and request extensions to my 30 days upon arrival to insure that I'm legal for the 90 days. My concern is that EVA will deny boarding if I do not have proof of onward travel. Any and all thoughts and/recommendations will be appreciated.
