Hello,

During the flight booking process I need to complete Traveller Information screen where the field Province is marked as optional.

I leave it blank but the next screen is an error message saying: "Sorry, we are unable to complete your booking. Billing address error - Province not supported. Enter a supported province."

What do I need to enter?

In Hungary we don't use Province as part of the address. Also my Profile is well saved with Province field left blank.

Thank you.
