If an airline comes to rescue stranded pax like those today at BHX then you can't really blame them for being late.
Yes they can be blamed. As a leasing company one would expect that the aircraft and crew are available on a standby basis. The necessity to react quickly to a callout reflects in the price of the service provided.
A company knows the disposition and availability of its aircraft and crew on an hourly basis. Hence when a request is submitted the reaction time should all ready be know and the service provided will reflect the nature of the company. This could be first or third rate. QED
