even if southwest were to start on aug 8...they may not be much cheaper (if at all) barring promotional pricing of some kind. fuel costs (they’ll probably be required to have more extra fuel than they’re used to), and airport fees might make it almost impossible for them to have cheap prices.
if they do actually have noticeably cheaper prices...it may be difficult to actually get tickets as there will probably be quite a few people trying to get them.
Not Atlanta.In all the markets that southwest enters everyone else is forced to lower their prices, I can't imagine that this market will be any different.
