There are one or two posts in the BRS forum that suggest the prices for Jet2 flights and holidays that have recently been put on sale at BRS are noticeably higher than those of easyJet. MAN has a significant Jet2 and easyJet presence. Are Jet2 prices generally higher than easyJet at MAN?
Also consider MAN not the only NW airport, people would also check fares with Easyjet from LPL
