BOS will definitely run over W07, as it received RDF from the Government.
It is planned to run 3x weekly, but may be more with one going via Knock.
SFB will no doubt return for W07 maybe 2 weekly. YHM is a cert to continue but maybe only 2 weekly from GLA as it will probably operate similar frequency from LGW and MAN.
YVR and YCC may not continue, but if they do I only see it being weekly flights.
JFK flights are on sale just now up to early Jan 08.
