Interesting to read back over this thread.
In particular my list of potential routes, which now sees some changes.
Charlotte will be served next year, as will Vienna.
Moscow is now served by Easyjet, Madrid still under Ryanair control, Tel Aviv with easyjet, and Tallinn with Ryanair.
In terms of a revised list, here is mine:
Hong Kong. Still unserved, still a huge market and still needed. Cathay Pacific have gone on public record to say MAN will be served when the A350 comes online, but, as ever, we wait with baited breath.
Phuket. Thomson have this winter opened up an LGW-HKT route and there is quite a demand from the North, so, there could be a chance to open the route from MAN.
Beijing. Air China have applied for a 4 weekly flight, and the China market is a well discussed one, so will not add any more here.
San Fransisco. A west coast USA route would be hugely beneficial to MAN. We have plugged many gaps in the other North America routes, so west coast is the next logical step.
Short Haul:
Bucharest. With the vast majority of Euro Capitals now served at MAN, and with the travel restrictions on Romania relaxed next year, this is the last of the 'large' euro capitals to be left.
Kiev. There seems to be a growing market in Ukraine and there are no direct routes north of London. There are many Ukrainians dotted around England, another option could be well utilised. However Wizz are the most likely to open up a UK region to Ukraine, and, well, we know they are not interested in MAN.
Casablanca: North Africa seems to be a strong market from MAN, and even has 2 scheduled routes to Morocco, but, one of North Arica's main cities is not served. Could be one for Royal Air Maroc (who do apply for slots every year at MAN), or Air Arabia Maroc who have also reportedly shown interest in MAN.
Other than those, I don't quite know what could be realistic additions on the short haul network, as it either involves duplication or is a small market. Quite a good position to be in really, I suppose.
