Talk about a solid bonus for those regional commuters in the Northeast. US Airways has announced a 5,000 point bonus for every 3 shuttle flights flown between now and the end of May. The 3 shuttle airports are BOS (Boston Logan), LGA (New York-Laguardia) and DCA (Washington, DC-Reagan).
This bonus can be earned up to a maximum of 10 times or 50,000 bonus points. The kicker here is the bonus is for every 3 segments, not round-trip flights.
I checked the lowest prices for shuttle flights in the time period and found $71 fares between DCA and BOS. If you did not have elite status on US Airways, those three flights would earn you a total of 194 miles for a price per mile of about 3.4 cents. You could buy US Airways miles cheaper than that by a bunch (usually just under 2 cents nowadays).
While I don’t see this being a good mileage run benefit based on the usual shuttle prices, this should be a really easy bonus to earn for anyone who travels these routes frequently.
