Sorry, should have posted a reply earlier.
On e-mailing the lanza air and booking a flight we were quoted €199 for the two of us. On checking with them the day before we travelled to Lanzarote the price had gone up to €250. Because of this we cancelled.
We had budgeted the €199 for the cost of our flight in with our spending money so the extra €50 was over what we took with us.
I must point out that the price is still a good price and I realise that costs do increase. However, we were unhappy with the fact that they did not inform us, they were going to tell us when we arrived for the flight.
