DALLAS — After facing a sudden shock to the system, the travel industry is sorting out a slew of inconveniences created by new air security restrictions. Airlines are adding beverage trays to their planes in case the ban on outside drinks creates additional demand onboard. Hotels are stocking up on toiletries that may have been confiscated at airport security checkpoints.

Travelers appeared to be taking it all in stride once the confusion from new restrictions faded.

Airport security lines that stretched for hours at some U.S. airports on Thursday returned closer to normal. Security checkpoints at Dallas/Fort Worth International Airport averaged five to 10 minutes yesterday, spokesman Ken Capps said.

"Our travelers adapted really quickly to the new rules," Capps said. "We had absolutely zero problems."

Airports and the Transportation Security Administration implemented the new restrictions on a few hours' notice early Thursday after British authorities disrupted an alleged terrorist plot to use common liquids to assemble explosives on board aircraft headed for the United States.

The rushed changes, which included a ban on most liquids, makeup and gels from carry-on luggage, created chaotic scenes as passengers dumped their toiletries ahead of their flights.

Hotels started responding yesterday after customers arrived without common toiletries such as toothbrushes and toothpaste.

Wyndham Hotels and Resorts said it would add contact lens solution, hair spray and hair gel to the toiletries it offers guests upon request. The hotel chain said an existing program already provides free deodorant and other items. It's even offering customers a free bottle of water at the front desk.

"It's something nice to give to guests when they arrive," spokeswoman Stacey Kennedy said.

The Hilton Anatole Hotel in Dallas stocked a meeting room with free toiletries such as shampoo, lotion and toothpaste that its customers might need.

Despite the bans, American Airlines Inc. said it was continuing to give passengers in first class and business class toiletry kits on board with toothpaste, hand lotion and other items.

The TSA cleared the items to be on board, much as it does with bottled water and sodas that are distributed by flight crews.

"We know what it is and where it came from," American spokesman Tim Smith said.

Connecting passengers could have them confiscated once removed from the plane, he said.

Most of American's flights were operating normally in the U.S., though some flights from London's Heathrow airport were still delayed 75 to 90 minutes yesterday, Smith said. Delays out of London's Gatwick airport were around 15 to 20 minutes.

Otherwise, the carrier saw few changes. The number of canceled bookings was "statistically insignificant," Smith said.

Across the industry, few passengers appeared to be canceling trips outright.

But vacationers make up much of the traffic during the summer travel season, so experts say it may take weeks to know whether the changes are hurting airlines.

On shorter routes in the U.S., the rule against carrying some toiletries in carry-on bags could lead some passengers to drive or take a train. "What you're paying for in air transportation is the saving of time," said David Stempler, president of the Air Travelers Association. "They may divert over to other means of transportation."
