Financial reasons.
Airplanes cost money sitting on the ground.
Just for the fun of it:
Airplane cost $240 million new
Depreciation to zero: 20 years
That's $12million/year just in depreciation.
$32,876/ day
$1,367/hr
$22.83/min.
This is just depreciation.
Doesn't include maintenance cost and insurance over 20 years.
Long haul airplanes can spend up to 16-18hrs in the air in a 24hr period.
Two legs plus turn around.
Some passengers flights are conducted at a loss and some may only make $300-$500 profit.
On an entire flight.
Any delay costs money.
Big money.
