The snaking lines of passengers waiting to board aircraft became synonymous with the brand. Southwest Airlines, the last holdout in a world of pre-reserved seating, has streamlined its process with announcement that a boarding pass number will now hold a passenger’s place in line. At the same time, Southwest introduced Business Select Fares, which, among other things, will enable passengers to board first. Not really a big deal…except for the fact that these slightly higher fares are fully refundable. Refundable fares? Now that’s news.
