One thing that is happening currently in BOS is good old "Southwest Effect". When they announced BOS-PHL, all the commuters to PHL breathed a sigh of relef as they now had a second, more reliable way of getting there. What actually happened is now ALL the PHL flights are full (there is a story making the rounds of systems must-riding 4 or 5 F/A/s out of BOS so they could make their trips) and the market upscales thanks to Southwest.
The problem US has always had for decades is they attempt to fill every seat at wharever fare they can grab utilizing the logic of "if we charge too much the people will book away". The part they always fail to realize is the other airlines are full as well. We've listened to the crap from marketing for years about "no yield to FL". Jet Blue should have really been named No Yield To Florida Airways, started by US Air. We virtually invented them and see to their growth on a continuing basis. US Air was the largest carrier at Logan for years and years. We are currently in the process of going to 7% of traffic at Logan. Guess who the largest carrier at Logan is......yup....JB. They've also started nonstops to most of the major west coast cities and are kicking the crap out of AA on those routes. We've screamed for years to pick up that stuff and management ignored us. I've always wondered at the logic of stuffing the airplane full at nonsensical prices and then burning the additional gas to lug it around, versus having sensible fares (like somebody's gonna blow up their vaca over $20.) and a few empty seats for last minute high-buck walkups, a lighter more fuel-efficient flight and (an unrealized biggie here) not beating the crap out of both the equipment and the workforce.
But after living out of Logan since '74, what the heck do I know.....?
