Just to clarify, the $98 RT fare is only good from May 9 to the middle of June. So imamicki2, your fare probably wouldn't fall under that category. Southwest probably posted that fare for their debut at Philly and Usair matched it. But I have a feeling that this type of fare war will go on for a while, so keep your ears and eyes open when it gets closer to your departure to see if you can get that credit!
