Southwest is extending its online bonus credit offer until Dec. 31. Rapid Rewards members who book online will receive one bonus credit for each roundtrip booked on http://www.southwest.com and flown by the end of the year (a half-credit bonus will be awarded if a one-way travel segment is booked). With this offer, three total credits will be earned for a roundtrip flight booked on southwest.com.

In addition, Rapid Rewards has unveiled several new online enhancements. Members who log onto the Rapid Rewards password-protected area of southwest.com will be taken to an “Account Snapshot” screen that showcases all of the travel details near and dear to a frequent flyer’s heart, including a detailed flight history, a list of scheduled trips, a frequent flight selector, and a Rapid Rewards credit summary.
