Airnerd/Fristclass,
The use of widebodies on high density routes is an interesting one. The ONLY widebody originally designed for both short haul and mediun range routes is the A300-B2 which emanated from an original Air France/BEA specification for a high density, rapid turn round aircraft that would primarily serve London-Paris and vv and also replace the Vanguard in BEA service and the Caravelle in Air France service on high frequency medium range routes, allowing for a reduction in frequency and costings.
The name Airbus stems from the concept and was first used succesfully by Air France from 1974 with the B2 version, BEA having dropped out. Lufthansa, Alitalia, Iberia and many other airlines have found the A300 excellent in the short/medium range role as this was what it was specifically designed for.
Boeing, having stuck with the 727, having seen initially very slow A300 sales and having watched PSA rapidly pull specially adapted L1011s off the California corridor routes designed a transcontinental airliner to supplement the short/medium haul 727 replacement (757), this being the 767 and entered the field with these 8 years after the A300 went into service. In a mirror like "reverse competition" move, Airbus launched the modified A310 as a medium/long haul 767 competitor and this, as a modification of the A300 was, like the 767 in short haul service, not ideal.
Boeing expected airlines finding the 747 too large for transcontinental routes would buy the 767 and replace the 727 with 757s, the aircraft having a single type endorsement due to cockpit commonality. This didn't happen as planned and the 757 was a slow seller initially, BA and Eastern being the only scheduled operators for a couple of years until Delta joined the party in 1984. In the mean time most US airlines wanted 767s for every type of operation as cockpit commonality was not as attractive as a single type. The need for long haul forced Boeing to adapt to ETOPS technology and use on short/medium high density routes involved a great deal of rethinking involving cycle life on many components.
Many Boeing customers worldwide bought A300s solely because it was the only widebody SPECIFICALLY designed for short/medium haul routes.
As to profitability, obviously airlines aim for profitable loads, whatever the size of aircraft but I've been on a Delta 767 operating Atlanta-Newark-Atlanta which arrived in Newark with 50 on board and took 35 of us back to Atlanta and that on a late summer Saturday early evening and I've been on AF Airbuses on London-Paris with less than 30% pax load factors.
What a purpose built aircraft will do is give a better, long term, chance of profitability across a range of economic conditions as the aircraft, when used in its intended role, is operating to an optimum, whatever the load.
ANSETT,
what has the number of accidents to do with the viability of the aircraft for the task or, come to that, with the safety of the aircraft? There has only been one accident to either type where there is a scintilla of doubt about the integrity of the aircraft and that is the 2001 AA A300 crash where there is a question re the fin. There are equal and even more pressing questions about both the ATC procedures and the AA crew's reaction to the encountered jet wash.
Other accidents to both types have had nothing to do with the integrity of the aircraft design, though there have been maintenance procedure questions.
