Not true! They don't sell all their seats at the same price. There are very few of the super cheap seats and as the price goes up the seat count goes up. There are plenty of restrictions on the low fares. One can see this by looking at any city pairs they fly to and what fares are sold and what is avialable. Read the fine print when booking and you can see the restrictions. The only thing that isn't restricted on WN is the number of bags of peanuts you get.GadgetFreak said:On Southwest, those prices are the for the whole plane with no restrictions.
