Our first flight was delayed out of Denver because of weather in Dallas, and then we were notified that our connecting flight had been cancelled to El Paso. Nothing to do but take the next flight later in the afternoon. What was supposed to be a late afternoon flight, was set back because of all the weather delays.....4 pm departure moved to 8:20 then to 9:50. We had no choice but sit all afternoon and wait. Well, the 9:50 flight was delayed coming in because of new storm approaching Dallas. We finally boarded at 10:30, and then one of the food service trucks parked against the plane had engine problems (they had to get a tow truck to pull it away).... All this is going on while a 'new' storm cell is approaching from the north. We had half a dozen or so, planes in front of us then finally got lined up on the runway. The pilot hit the throttles, and was just starting to accelerate when he pulled the throttles back and turned off the runway. Pilot announced we would get back in line to attempt another takeoff, if the storm would let us. 45 minutes later we were finally in the air.....got to El Paso and fell into bed at 1:30 in the morning. We are on the way to the border now to try get papers for the suburban, as we have to get it in my name to enter Mexico.......more later.
