For jetBlue flights, use their “FALLSALE” coupon-code (expires 7/27 at about 1:00am ct) for $25 off one-way, $50 off round-trips. More details about the coupon at jetBlue.com. This sale is being aggressively matched by Untied. Before you finalize your purchase, you may want to do a quick check to see if other airlines have a better deal.
JetBlue’s “Basic” fares only allow a small personal item (17 x 13 x 8 inches), like a Jansport SuperBreak backpack without a fee. A regular sized carry-on bag will incur a bag fee. To avoid bag fees, consider using a credit card with the “first free checked bag” perk.
