Hey there, I just booked a flight start July from London to Sydney via Expedia on Thai Airways.

As a monumental mistake I booked my ticket as Ben rather than Benjamin as on my passport.

I've checked it out, seems like I might be ok and might not. Also read that if you ask for a name correction within 24 hours, you might be ok.
Problem is I can't get hold of anyone at Thai Airways.

I'm actually contemplating just changing my name by deedpoll and getting a new passport, as I'm certain I can do that in time worst case.

Any suggestions on what to do/if I'll be ok? Flying first, booked on Expedia at a pretty good price.

Thanks
