United Continental (NYSE:UAL) landed itself in hot water last week after bumping
 a customer from his flight in an unusually cruel manner. David Dao was already 
seated on the plane, which was set to fly from Chicago to Louisville, when he was
 bumped to a flight the next day. When he refused to get up, airline employees 
called the police, who dragged him from his seat and down the aisle.
The videos of this incident are truly shocking. As a result, United now finds itself 
in the crosshairs of lawmakers and regulators, while many (former) customers have
 vowed that they will never again fly United.
What makes this situation particularly sad is that it was totally avoidable. For little
 or no additional cost, the airline could have made everyone happy by chartering 
a private jet.

United was in a tough spot

The incident last Sunday began when four airline crew members showed up at 
the gate looking for seats to Louisville after passengers had boarded the flight.
 United would have had to cancel a Monday morning flight from Louisville to
 Newark -- stranding dozens of passengers -- if those crew members hadn't 
made it to Louisville that night.

Many people are willing to give up their seats on overbooked flights in exchange
 for vouchers toward future travel. This allows the airlines to keep everyone happy
 while getting around the stiff regulations governing compensation for involuntary
 denied boardings.
Unfortunately, there were no volunteers in this case. Before last Sunday's
 incident, United had offered customers $400 in vouchers (plus a hotel room)
 and then went up to $800 in an attempt to find volunteers to travel the next day,
 but nobody took the bait.

A private jet would do the trick

It may have seemed to the United staff on the ground that they had no choice 
but to bump four passengers from the flight. But a private jet could have solved
 the problem at a relatively modest cost.
The Department of Transportation's rules on overbooking required United to 
pay cash compensation of $1,350 each to the four passengers that the carrier 
bumped, or $5,400 total. By contrast, the typical cost to charter a small private
 jet for the roughly one-hour flight from Chicago to Louisville would be about $6,000.
In fact, the founders of private aviation start-up FlyOtto recently invited United
 to try their service for free to reposition crews. FlyOtto would have been able to
 fly four people from Chicago to Louisville for just $2,930, albeit on a turboprop 
rather than a jet.

Using private jets isn't unheard of

In recent years, Delta Air Lines (NYSE:DAL) has pioneered the concept of using
 private jets alongside its regular commercial fleet. This works especially well for 
Delta, because it has an in-house private jet subsidiary: Delta Private Jets.
Two years ago, Delta began a pilot program to give elite frequent fliers the 
opportunity to upgrade to a seat on a private jet for as little as $300 one-way 
on certain flights. Private jets often fly empty on "re-positioning" flights, as they 
go to make their next pick-up. Delta is using these empty flights to offer a 
once-in-a-lifetime experience to loyal customers who happen to be going the
 same way.

Delta Air Lines has also used its private jet fleet to pitch in during operational
 disruptions. For example, Delta flew more than 40 customers on private jets 
after a major technology outage caused numerous flight cancellations last August.

A better way

United doesn't have its own private jets, but it could have chartered one for 
roughly the same amount it would have had to pay four passengers to
 compensate for "bumping" them. In all likelihood, United could have enticed 
a few passengers to pay more to upgrade to a private jet -- and it certainly 
wouldn't have had trouble finding volunteers to fly private!
Now, the damage from this misstep could reach billions of dollars if large
 numbers of people start avoiding United Airlines flights. United executives 
probably already regret that they didn't have policies in place for using private
 jets as a last resort in "oversold" situations.
