Anyone going from DFW to Orlando this winter/early spring, should DEFINITELY check these airfares. We got tickets for our spring break trip in March for $101.24 - amazing since we hardly ever get to fly for less than $200. There are also deals in December, January etc.
I have been monitoring these fares for the last 2 months every day and I have only seen them go below $300 once. So, this is just AMAZING!!
The only problem we had was booking our infant discounted rate. Delta's website can't book these and it says to call. We did but by the time we were on hold etc. the fare had gone up so much that her ticket at half price was more than mine at full price. We tried booking one more ticket on line but those fares were gone also so we ended up paying $119 for her (still not bad but ironic that it is more than my ticket).
Good luck,
