We have never charged for our famous "Night Time tours of the Peak District " (aka hotacs) - perhaps the tour operators should have reps in the check-in queues selling these as optional excursions in the event of delayed flights.....
Passengers are never happy with how delayed flights are managed - read the history of Court Line and you see that pax were complaining in the same way in 1972 as they are today.
In dealing with re-routes, delays and diversions we see pax at their worst and can easily identify who will be trouble makers. The most gentle people can become monsters when their flight is delayed. How many times have we all heard the " I've lost half a day of my holiday...and I want compensation " ?
In my years in dealing with delays the best thing to do is to point out that :
1. There is no compromise on aircaft safety
2. There is no airline equivalent of Hertz
These are usually quite effective in giving the distressed pax a reality check.
