WASHINGTON, Nov 5 (Reuters) - The head of a trade group

representing major U.S. airlines told Reuters on Wednesday

carriers are beginning to see a drop-off in passenger bookings

as a government shutdown hit a record 36th day on Wednesday.

"We started seeing as an industry pull back on folks booking

their travel plans just over a week ago and it's growing a

little bit every day," said Chris Sununu, who heads Airlines for

America that represents American Airlines ( AAL ), United

Airlines, Southwest Airlines ( LUV ), Delta Air Lines ( DAL )

, JetBlue Airways ( JBLU ) and other major carriers,

adding carriers are not seeing a jump in cancellations.

"We're trying to encourage people to stick with their

bookings, stick with their travel plans."
