Paxy.....I understand your frustration, believe me, however that's not how crewing works unfortunately.
There's not such a thing as "those standby crew were not entitled to that 3 day trip", as once they call out somebody to do any kind of trip it can be easier and less complicated (from a planning point of view) to have the standby crew do the rest of the trip and transfer their standby's to the crew who got delayed.
Again, I understand your frustration very well, I know how you feel, however the company doesn't care whether you get annoyed or not, they have an operation to run and try to do it in the easiest, cheapest way possible, and in this case most likely passing the rest of their standby's to you and your crew was just that.
Morale is going really down at LGW, it's such a shame
