JetBlue is having a " Mother's Day Sale" but some of these are not the lowest fares we've seen on the featured routes, not by a long shot.
New York/Burbank is $169 each way; Boston/Phoenix is $134 each way.
And they're not the lowest available on some routes. For example, US Air flies Boston/Phoenix nonstop, as JetBlue does, for $109 each way.
The fares between Newark and Florida are near their historic lows, however, at $59 each way.
The fine print: Fare requires a 14-day advance purchase. Travel must be completed by June 13, 2007. Travel must take place on Tuesday, Wednesday, and/or Saturday. Fares not available between May 23, 2007 and May 30, 2007. Fares do not include Passenger Facility Charges of up to $9 each way, September 11th Security Fees of up to $5 each way and a Federal Segment Tax of $3.40 per domestic segment. A segment is a takeoff and landing. Puerto Rico fares also do not include a excise tax of $15.10 each way. International fares also do not include government fees and taxes of up to $72.05 each way.
