Higher pre-authorization for booking transaction

Hi, I made an online booking on, and I've recently noticed a transaction's exchange rate is WRONG.

Pending Authorizations

Date: 12/14/2014 02:23 T103482838

Pre-Auth Transaction-POS Signature Purchase International

Local Currency Amount: [European Economic and Monetary Union (EMU), Euro: 621.0]
Amount to charge: $947.08

Conversion rate is 947.08/621.0 = 1.57! It has never been so high in the history, how is that possible? WTF?!

On official MasterCards's site USD/EUR rate is 1.2396

I'm very disappointed. Please explain, how can I avoid this.

    Hi Pavel,

    When you make a purchase with certain types of merchants, the charge may be pre-authorized at up to 20% higher than the actual amount. This is only for the pending authorization, to ensure that your card will have sufficient funds to complete the purchase. Once the merchant charges the funds, this pending authorization will be released and your card will be charged for the actual amount.

    This is most common with hospitality merchants (hotels, travel reservations, restaurants, etc).
