With mainline shrinking capacity, UAX is taking over more routes....

So here's the game:

Find the longest UAX-only routing. Rules are simple. The most direct route between departure and destination cities must have all segments served only by UAX (no mainline flights).

For example, YEG-ORD-JAX is 2283 actual miles with no mainline service available between either city pairs (no non-stops from YEG-JAX, either ).
