Too bad you are not entitled to any relaxation on the refund rules set by the airlines, you shall lose some or most of what you paid. This would be understandable to some extent if the airlines reciprocated. But when it is their turn, and the flight gets delayed or cancelled due to similar problems, the best you can hope for is a grudging refund. Which also usually takes forever and a month of Sundays added on. Or comes with lock-in conditions, usually compelling you to travel by the same airline within a limited period.
