For example, I found seats departing Los Angeles LAX on Wednesday, November 7, returning from Baltimore BWI on Tuesday, November 13.
Other dates are also available for travel on Tuesdays and Wednesdays in November and December, excluding peak holiday travel.
You may find similar fares on Spirit or United, though do keep in mind that Southwest allows for two free checked bags, while Spirit and United only include a small personal item. Southwest is hands down the better deal in this case. For more info on flying Southwest, check out our guide on How to Fly Southwest Airlines (And Get the Seat You Want).
