She paid for her own flight ticket to meeting him...

Guys,

the story began and am acting on behalf her as a friend!

anyway her bf was in Sydney Australia, and she's from Malaysia.
they relation almost 6 months now, love each other,

so the main story is, he's always came to Malaysia visiting her and traveling somewhere outside of the country for vacation, happily couple!

so, she might want to visit him in next year time, so should she pay for her own ticket to fly and meet him?

and he did not offer to pay..surely he will pay everything accomodation, foods ..etc while she's there!

is that fair enough? she paid the ticket and he pay the others?

any comments? or is this normal?
