Bristol and Leeds have similar loads to each other ranging from >70% in summer to <50% in winter. Bristol always does slightly better than Leeds. I would describe them both as quite marginal routes from Knock in the winter months.
Reus did extremely well last summer, >85% in July and August and still decent for the other months it ran (May - Oct), much more competition in terms of sun routes this year though proximity to Barcelona gives this route something that the others cannot offer. All reports so far indicate that Edinburgh is flying but it is to early yet to be able to back that up with figures.
Flybe have added some more connections through Edinburgh - Jersey, Guernsey, Inverness and Stornaway can now be booked from Knock. I have no idea whether there is much of a take up on these connections but there are now 13 in total on offer via Edinburgh.
