Doubt it'll be MON, didn't Tim Jeans say that they were cutting back to their main core airports (from memory LGW, LTN, BHX, MAN). This was why they withdrew from BLK. Only "non-core" scheduled route will be AGP-ABZ, & even that may be in doubt if GSM muscle in.
Back to DTV. I still say Jet2 would be the main airline to fill the void left by Baby. GSM could also help, noting that they are to fly TFS-MME this winter.
