The question was would a Holiday, Package, IT flight (with 737 or A320 sized a/c) from Newcastle, Glasgow or Leeds Bradford work only in the summer months bringing domestic stay-cation tourists from the North down to the South Coast - specifically for a summer beach holiday in Bournemouth?
Newquay seems to support this theory (albeit with Flybe) but Bournemouth has over 7m tourists (12m if you include Poole and surrounding area) a year mostly from domestic UK.
