12 months ago, LJ asked me how many routes I had found with demand for 2 daily A380s. From major tier 1 and 2 global cities, any route to another major capital in a major country will provide enough. LGW-JFK, LGW-MAD, LGW-DXB. Just to name 3. I would fly A380s to all aside from madrid because madrid is WAY TOO short for an a380 to justify it. I'd just flood the frequencies instead
