Holidaymakers: Protect us from another XL

Pertinent

I must admit, this is pertinent to me at the moment.

My mother and father have decided to go away next summer to Spain to stay in my Aunties villa, they decided to book flights now. I wanted to wait but was told "the prices would go up". They've booked with Easyjet (paying on their credit card for safety) and I am now going to spend the next nine months hoping Stelios has got enough money!
