Just last week a number of different airlines were forced to make cancellations and delay flights due to serious weather conditions. While Southwest Airlines was among those in distress, the airline suffered an extra problem when it was forced to halt all departures.

Within the last week, Southwest has canceled 758 flights to high traffic destinations such as Dallas Love Field (DAL), Denver International Airport (DEN), Chicago Midway (MDW), Phoenix Sky Harbor (PHX), Las Vegas McCarran (LAS), Orlando International Airport (MCO), and Los Angeles International Airport (LAX).

Southwest Airlines' flights for the first time can be booked on Booking Holdings' online travel websites, including Priceline, Booking.com and Agoda.

Priceline is the second online travel agency to partner with Southwest as the carrier looks to widen its distribution channels amid major shifts in its business model.

Just two months after ending its long-standing “Bags Fly Free” policy, the airline has announced when it will roll out assigned seating — a significant shift from its traditional boarding process. For decades, Southwest used a first-come, first-served system, along with free checked bags, that set it apart from its competitors.

Over the past few months Southwest Airlines has made two significant - and controversial - changes by ending free checked bags and revamping its boarding process. Southwest charges $35 for a first checked bag and $45 for a second checked bag.
