Round-trip airfare between Boston and Philadelphia is doubling as Southwest Airlines discontinues the route this week and once again leaves US Airways as the only carrier flying nonstop between the two cities
The lowest regular round-trip nonstop fare will jump to $520 from about $260, according to airline websites. Southwest will discontinue the Boston to Philadelphia route as of Saturday. Southwest has dropped five routes out of Philadelphia this year, including Manchester, Providence, Pittsburgh, and Jacksonville.
“The flights weren’t performing up to our satisfaction, and we can be more productive and profitable shifting the aircraft to other routes,’’ said spokesman Chris Mainz.
