Just want to make a few points about the "risk" to restarting flights to Sharm.
El-Arish (location of the recent attacks against Egyptian Soldiers) is approximately 300 miles from Sharm El Sheikh (Hurghada is another 50 miles further south, across the water). The region of North Sinai has historically been very politically unstable for various reasons. Sharm is closer to and is surrounded by friendly nations such as Jordan, Saudi Arabia and the remainder of Egypt. Egypt and Egyptians in general know how much tourism means to their country and are taking unprecedented steps to protect those interests. It is worth noting that all tourist destinations in Egypt are considered safe to visit (including Abu Simbel - site of previous attacks against western tourists) and the region of South Sinai was one of the few regions in Egypt that did not see violent protests for and against the Muslim Brotherhood and, previously, Hosni Mubarak.
The risk to tourists in that part of Egypt is not much different to that in most parts of Europe, insofar as the fact is that terrorist activity could happen anywhere, at any time (who saw the possibility of a passenger airline being shot down in Europe, for example?). There is currently as much advice on visiting Paris as there is visiting Sharm and I bet nobody would bat an eyelid at visiting France, despite the numerous threats made against it by Islamist Organisations.
For your information, Nicosia in Cyprus is the same distance (300 miles) from Kobane (which has just been cleared of IS) in Syria. Malta is only about 250 miles from Tripoli, Lybia - as is Enfidha, Tunisia, both of which are considered safe to visit. During the troubles in Northern Ireland (a time at which co-ordinated attacks were carried out on soldiers and citizens in the rest of the UK, including here in West Yorkshire), it was not suggested that the UK was an unsafe place to visit, despite Belfast being only 320 miles from London. As far as I am concerned, the world is no less safe now than it was 30 years ago. It is simply different people doing things for different reasons.
Half the problems the world faces are caused by a simple lack of knowledge or understanding. Let's join Jet2 in being part of the solution and supporting Egypt going about their normal business. As it has been pointed out already, Manchester has many weekly departures to the region. Demand is there to be had.
