We as an industry have gotten to a point where our customers think that we can deliver a 100% on-time, guaranteed and safe flight and arrival. Only we ourselves know what can go wrong and it sometimes will. That not all the variables and threats we can control.
During one of my flights we had to cancel the flight from BKK, bound for Europe, as some catering truck driver punctuated the hull and we needed an extra nite stop. Leaving BKK back to the city I talked to a father with two accompanied kids and he said the forced (but paid) stopover in the hotel posed problems to him as the extra expenses like calling home (was in the pre-mobile phone era) was impossible. He had spent ALL his money in BKK, till the last dime! Never occurred to him anything out-of-the-expected COULD happen to them. Just reach the airport, "hop" in the plane, sit the 11 hours out and be home.
