Onyx - Southend-Leeds takes 4 hours by train so would need a very large corporate with regular daily staff transport requirements for such a route to exist. Humberside has very few domestic routes right now - Southend is not a centre for oil/gas so can't really see SEN-HUY being top of the list.
Flybe from Southend to Scotland is a little more interesting. Easyjet are dropping Belfast and struggling with SEN-EDI - if they give up on the EDI route then there might possibly be room for Flybe to step in instead on a 78 seat instead of a 156 seat aircraft. Glasgow on a Q400 might work as well but Southend-Inverness seems rather ambitious...
