EI will have to be more competitive on their fares. A recent flight from SFO / DUB only had about 60 PAX. Doesn't seem like a successful entry to a new market. There is a price tipping point for individuals / families that make going via FRA, LHR, AMS, CDG or with the likes of WOW more attractive Testing the market for DUB- LAS will indeed need some competitive pricing.
SFO is very successful, one flight is not a good judgment. It's operating over 90% over the summer, 80-85% outside this with prehaps Jan/Feb slightly but it's operating at a higher frequency Q1 than in 2016.
I can't imagine too many Business Class tickets to Las Vegas. Would it be a similar offering to Orlando? DFW would seem to have an advantage in this regard.
If they are going to start looking at long-haul leisure destinations, has anywhere in the Caribbean ever been considered?
Will be priced like MCO I suspect which does well and couldn't see freq been more than x3 weekly.
