Heightened security to worsen travel woes

Tighter restrictions on carry-on luggage, including bans on liquids, will disrupt air travel for at least several days and make it even more of a headache for passengers already sick of crowded planes and long lines, experts said.

U.S. security officials banned passengers from carrying any liquids onto planes after British officials said they foiled a plot to bomb flights to the United States on Thursday.

The new restrictions were sure to cause major disruptions for at least two or three days at airport security checkpoints as screeners scour carry-on bags for drinks, hair gels and lotions, experts said.
