Shoe fetish???
Joking, listen, there's a small chance to find this woman this way. But it's very small. The best solution was already given above. Go to the airline's airport office, somewhere in the basement probably, very early or late in the day, find some sweet Filipina girl working there and impress her with your intentions towards the Romanian passenger (Filipinas usually have soft hearts, she may take pity on a love story), if she thinks she can help you then give her also some money (important! they may have soft hearts but also need cash
) and ask her to look up the passenger list for the name/nationality (you remember what seat numbers you were in, also maybe?).
This is fun.
