The elite line has been extremely helpful to me the last two days, and has rebooked me three times now without charging me. I may have been lucky, but after explaining why I needed to rebook a third time (decided it was better to stay where I was rather than fly back to IAH early and then drive up to a family member's home north of the Houston area to ride out the storm) I was rebooked to fly back to IAH on Sunday without question.
