About 2-3 years ago there was an issue with a RYR flight in Barcelona BCN, they arrived with less than minimum fuel and requested to shoot APP and land whilst other aircrafts were on APP following the normal waiting pattern to land.
One IBERIA captain told them on frecuency that if they wanted to land first they should declare minimum fuel and there would be no problem for others to let them go down first.
The RYR diverted to Gerona GRO.
