Don't know if they have the aircraft for the whole tournament but it seems unlikely. I suspect the aircraft may be subbed onto a return NRT service or a World Cup charter during the two weeks between England arriving in Japan and being knocked out! The cabin crew are being selected from those on standby at home whilst the flight crew will probably be the traditional collection of management pilots off on a jolly. They will have understandably pressing reasons for travelling all over Japan/S. Korea to check on airport suitability, taxy routings, etc. etc. in advance of the teams arrival, just like they did when they took HRH to Oz! Nice work if you can get it, which you can't.
