I've just looked at Panorama's online brochure. Their Tunisia programme for this summer was to be just one weekly flight from DUB. As much as it is likely Thomas Cook/Thomson are going to have to cut back on their programmes from the UK, I wouldn't assume one dropped flight from Ireland, and 6 dropped flights by Jet 2, means Thomas Cook and Thomson will cut Tunisia entirely from the UK. Possible, but I don't think it's certain.
