Unstable and rising fuel prices are leading to upheavals in the airline industry, with collapses of large companies such as that which occurred on Thursday becoming more common. This will lead to cuts (or an end) to cheap flights to distant places like Bulgaria and to obscure destinations nearer home.

What will they be worth when the cheap flights stop?
