Because of the way DFW is set and because the airport is so sprawling it is an absolute necessity know the arrival gate when picking someone up. Without that you are lost. We are new to Dallas and it is almost impossible to get an accurate gate designation. I must leave in 30 minutes to pick up my party - and their flight arrival info isn't yet posted on the airport website. In light of the way the airport is set up DFW must do a better job of informing patrons of arrival gates - and not 10 minutes before the flight lands! It sucks right now.
