I guess we should be grateful for the routes we have now to EWR & DXB. As well as other destinations that we didn't serve previously.
I recall years ago in the summer months we had operations not just from TOM & TCX. But also Excel Airways, Air Scandic, Flyjet etc. (Albeit at different times) Then we also had far more operators coming in from overseas, such as Onur Air (didn't they send the A300 every Sunday for a season?) Freebird, Pegasus, Spanair, Iberworld, Air Europa, Eurocypria, Helios, South Atlantic Airways at one point? Islandflug, MD Airlines, Volar/LTE, Monarch (weekly charters to SFB/POP/CUN at one point). Probably missed lots of others off too. I know many of them are no longer around.
I guess much of the work has been taken up by other carriers expanding, Jet2 increasing its size at NCL. It's a shame that we haven't had much in terms of expansion from our legacy based carriers. But we can hope for the future.
