Don't expect to see p.s. or anything approaching it anytime in the next 3-5 years on TCONs to BOS, IAD or EWR (the latter two being hubs).
1. No competition. Neither AA nor DL offer their premium service other than xJFK.
2. Likely no market for paid F other than LAX (movie industry) and SFO (private equity + tech sector).
VX offers a better product , and B6 is looking to expand Mint to BOS-SFO once they finish deploying out the JFK-SFO/LAX. BOS/SFO has plenty of VC/Tech/Pharma traffic.
