JMC's order was 2 plus 3 options.
I think the Boeing website will mean "despatch reliability" rather than on-time performance - manufacturers never rate aircraft by "on-time departures" as this would include weather, ATC, passenger and crew related delays - if you inclued these figures it would make the plane seem less reiable than it really was. Only "despatch reliability" is measurd, which is;
How often is there a technical problem preventing the plane from leaving when it is supposed to?
Navion is correct, with such a small fleet, the figures are impressive. If you have 1000 757-200 flights and one is delayed due to techical problems, that gives a depatch reliability of 99.9%. If you have 10 757-300 flights and one is delayed, despatch reliability is only 90%.
As to the comments about FAO, PMI, ACE, FNC and TFS not having poor facilities - I'd have to disagree. Only Tenerife and Arrecife have airbridges and then only a few, most pax have to be bussed to their aircraft. This creates delays, baggage handling is generally slowed for the same reason and these airports get VERY over-congested, both with people and with aircraft. For exampe, I usually travel to Tenerife on an early morning flight from the UK (departing between 07.30 and 08.30) In my last 8 trips, the flight has left the UK on time and arrived in TFS either on-time or early. On my return trip, the plane has each time arrived early for the ruturn trip and boarding usually starts on time, however boarding with busses takes ages. When everyone is onboard, there is usually a 15-20 minute wait for taxi clearence, then you join the que of 3-6 aircraft on the taxiway awaiting takeoff, another 15-30 minte wait. In 8 trips the delays in leaving Tenerife have been between 30 mins and 2 hours - these airports definately don't have good passenger facilities! To get a plane off on time is a real challenge!
