My father is taking a business trip on Continental from LAX to EZE in Argentina. The flight has one flight number, with a change of planes in Houston. If the first flight is late in arriving in Houston, can the second flight take off before the first flight lands? That is, is it okay to have two flights in the air at the same time with the same flight designation? Could he miss the second flight, or do they hold up the second flight since it has the same flight number as the first?
Thanks.
