Manchester is known for its beutiful weather so it is the first port of call for a lot of diversions! Seriously though the airport routinely handles 747’s so it has the capacity and facilitys for bad days. This was only a fuel stop (Splash and dash) but if this one had to stay we would have to deal with 300+ pax. Most airports would struggle to cope. Some airfield wouldn’t have steps high enough to get on board!.
