The fact that they are being vague about Route 2 should in itself send out warning signs. If they are asking you to commit a six figure sum to your training but won't commit to telling you what your chances of proceeding down a certain training path, that really doesn't show them in a good light.
My advice, wait for Aer Lingus, which should open in a couple of months, or even for Virgin Atlantic which generally comes alive around November.
