I suspect the dropped TFS flight is to do with the First Choice winter pull out from HUY (except a Lapland flight) announced some weeks ago. They shared with Airtours to TFS in winter. The 2nd, now dropped, flight was shared between Thomson and Thomas Cook. My guess is that Thomas Cook are now sharing with Airtours (due to their merger) and Thomson, with no sharer, have therefore axed their flight and can still offer passengers DSA-TFS
