Leeds Bradford has enjoyed a continuous multi-daily service to Amsterdam since 1976, when Air Anglia took on the route from British Airways. Effectively , LBA-AMS has been flown by the same operator since then, from Air Anglia, Air UK, KLM UK and now KLM City hopper, now a part of the same KLM-Air France empire. 48 years in and LBA doesn't see the Air France side of the partnership either! Jet2 fly to Paris a few times a week, no multiple daily flights and not daily. I'm not sure Jet2 are that serious about the route. It's not that many years since British Midland flew LBA-CDG up to three times a day. And Brussels too.
