I fly with them all the time. They are prob 20% of BA prices, 60% of easyjet and other cheap airline prices.
yeah, tickets aren't usually £10 like the marketing speak. But how the fuck would you expect an airline to run for £10 a ticket. They are still cheaper than anyone else.
Their headline price is usually cheaper, but by the time you add the hidden extras there is very little difference, except for the terrible service and horrible seats.
