One-way fares for this one start at $39 from Boston's Logan International Airport for travel from Dec. 6-Feb. 15, and tickets must be purchased by midnight. Blackout dates are Dec. 16-Jan. 3 and all Fridays and Sundays, and discounts require a 7-day advance purchase. Here is the fine print.
This sale comes one day after Southwest-Airtran launched a four-day promotion, with similar restrictions -- most salient being the blackout days around the Christmas-New Year's holidays (although some with more flexible schedules might be able to work around Southwest-Airtran's Dec. 22-Jan. 3 dates).
