 It appears to be an easier travel day so far. There are more than 300 flight cancellations, but yesterday, 1,800 were scrapped and there were more than 7,000 flight delays. Following Sunday's record day after the 4th of July, when TSA passenger screenings at airports topped 3 million for the first time, there's been yet another mishap on a Boeing plane. The flight from LAX to Denver International Airport did reach its destination safely.
