Hey all,

I have an upcoming flight (Edinburgh - Bergen) booked under the Fly rate. That rate allows for 15kg hold luggage. It is on an Embraer, so there isn't a worry about actual space down in the hold.

More than likely my bag will be 20kg.

If I add another 15kg bag (£20), could they just use that 15+15kg as one bag?
Do they charge a flat per-kg over?

Upgrading to Fly Flex (23kg) is about an extra £45, but I'm looking for the cheapest option.
