I was recently delayed approximately 20 hours by Lufthansa (going from Reykjavik, Iceland to Frankfurt, Germany), which required me to book two additional hotel rooms (one in in Reykjavik, another in Frankfurt). I had a hotel room in Frankfurt already, but wasn't able to move the reservation because the flight delay was made after the deadline (48 hours, IIRC) to adjust. Hence I missed one hotel stay and had to book a room for the next day.

I'm trying to submit for compensation. The problem is that their delay caused expenses in three different currencies, and their form only has an option to select 1 currency.

Does anyone know the correct way to submit multiple currencies for compensation? Or is the compensation supposed to be the currency of my country, and I convert totals from the receipts to that?
