The route
What the journey actually looks like
Direct or connecting, how far the route really runs, and what happens when a connection is missed.
- Direct or connecting
- 50% of the services we sell on this corridor run through without a change. The remaining 50% involve one connection.
- How far it really runs
- The route covers 1,151 km against 1,117 km in a straight line, a detour of 3 percent. Track and road geometry account for the difference.
- Where the change is
- Connections are made at Las Vegas, Santa Ana. The gap between arriving and leaving is 99 minutes, of which about 5 is walking.
- If the connection is missed
- The tightest connection we sell here has a 10 percent chance of not being made on the timetable alone. Both legs are sold on one booking, so a missed connection is ours to fix and you are rebooked at no charge.
- First and last departure
- The first service of the day leaves Mesa at 06:29 and the last at 14:42, across 4 departures. The return direction keeps its own timetable, so the times back are not these times reversed.

Where these numbers come from
Observed service A carrier record shows this named operator serving this named pair, and we carry that through unchanged.
Schedules, seat counts and fares are generated by our own model until the supplier contracts are signed. Places, coordinates, operators, which operator serves which pair, and every distance are real. We would rather say that on every page than let a modeled number pass for a filed one.
