Don’t think competition is good for a route?
In the first quarter this year, the most expensive market in the country, per mile, was Boston to Philadelphia, a US Airways-dominated route, where the average fare was a whopping $684. Southwest began serving that route in June.
And now? US Airways’ highest coach fare is $281 round-trip—$400 less than its first-quarter average fare.
The most-expensive average domestic ticket in the first quarter was $786 for round-trip flights between San Francisco and Philadelphia, according to the DOT. That 2,521-mile route is dominated by United and US Airways, who are competitors but also partners in the Star Alliance. Fly to Boston from San Francisco—183 miles farther by air than Philadelphia—and you paid an average $296 less round-trip in the first quarter, according to DOT. The difference: JetBlue Airways has 17% of the San Francisco-Boston market, but none of the San Francisco-Philadelphia market.
