The interesting point is, that with master card you can't pay LH tickets in all LH stations anymore.

Most propably it's only in strange locations but last weekend I couldn't pay my ticket in Tehran with my HON-MC. They are for some obscure reasons just allowed to accepet Amex (!) and Visa.

They told me also, that in the last couple of days this has happened with several customers... And in the beginning they didn't even know why the SEN-MCs where rejected suddenly this year...
