US Airways started this week an Internet fare war on their New York shuttle service to Boston and DC by cutting its round-trip advance booking fares 44% to $138 from $248.
Delta Air Lines has responded with a $141 fare between DC and New York, while the other major competitor to US Airways, Amtrak, is offering $126 round trip.
US Airways has also cut its weekend round-trip shuttle fares by 60 percent for this weekend and the next as part of its annual holiday sale. The $98 tickets does not require advance purchase but must be bought at the airline’s Web site.
