If you've booked DIY like I did then you do have to unfortunately fend for yourself.
I was in Tenerife when I heard Glasgow and Irish Airports was shut,we weren't due to fly out til the Friday so we were lucky and got home to Glasgow that day but on the day of closure we met couples and families who had returned to the hotel to book in again at their own cost after being sent away from the airport with only a letter that only told them their flight was cancelled due to volcanic ash,these people weren't even aware of the situation til they got to the airport.
I'm don't know if they were offered any form of compensation afterwards or if they could claim back any money spent but what if they had no money left to pay for an extra couple of nights?The lack of information for those booking flights only was appalling.
I was extremely lucky as I was travelling myself with a young child and wouldn't have known were to turn if things had went pear shaped for us,as I said we were DIY and had 50euros left the day we went home.
If you have booked DIY,please keep money by just in case or have someone back home who can send you some funds and keep all your receipts so you can try to claim back any money you have spent on food and accommodation.
A huge saving booking independantly could end up costing a fortune,so please everyone be prepared.
If you make it on your hols,hope you have a fab time and return safely and a speedy return for those currently affected.Take care xx
