there are 'informal' mamas there .. as they have always been.
Well, sorry to crash your party, I bought enough tickets on Cebu Pac and none of them needed my CC copy.
And I wouldn't trust any girl with my ID/CC info ..
Trust me on that .. you never know when you gonna get whacked including using the info to trace you down and .. not to scare your pants, but .. also to threaten you showing the info as proof-of-closeness ..
Don't give it ..
if she insists, tell her find somebody to buy her the ticket

problem solved.
And in PH, since no National IC, they can produce any form of identification, including 'home made' ones as long as it has a photo

or her PRC id, or her former work place id .. or her school id .. etc. etc.
Fret not much says me .. after having bought more than 6 dozen or more domestic tickets .. don't ask my why !!!!!!!!!
