Is it not two flights? One from STN on the Saturday at 11:55 then from NOC on the Monday at 16:40. Those flights will probably carry the London team with some of their lads out of pocket due to these additional matches from taking days off work.
The team want to arrive relaxed and refreshed and not have to put for with the FR scrum for seats on board etc
which is why EI Regional will fly them in on a charter.
