TSR2....not quite a direct comparison...Olympic will have contracted a block seat rate with Jet2 (assuming they aren't scraping their site or worse, ghosting the schedule of Jet2 only to move pax later on in the hope of contracting rates with a carrier at more favourable rates..they wouldn't be the first...)..Cosmos do not have a contracted block rate with ZB but sell depending on how the overall Monarch stock is selling (as part of the group). From your observations it appears that Monarch Group is in pretty good shape compared to Olympic/Jet2....Maybe Olympic are this years Goldtrail?
