I understand the limitations on 'over water' first-leg and through existing bases.
Question about the MCO ER flying: How many MSP/DTW/LAX/JFK/etc trips start or end with an MCO leg? Do these legs become MCO-XXX-MCO turns easily or do they just get siphoned off and built into the MCO trips? Also, the ER has 'over water' trips out of RDU, BOS and PDX (off the top of my head) that could be built into MCO trips.
My biggest concern about VB's is that the flying has to come FROM somewhere. How is it going to affect the trip construction in existing bases?
