Japanese airlines and travel agencies said Friday there has been no significant impact on the industry since the discovery of a terrorist plot targeting jetliners in Britain the previous day.</PARAGRAPH> <PHOTO> <TABLE WIDTH='250' ALIGN='RIGHT' BORDER='0'> <TR> <TD><IMG ALT='News photo' BORDER='0' SRC='../images/photos2006/nn20060812a2a.jpg' WIDTH='250' HEIGHT='189'/></TD> </TR> <TR> <TD><FONT SIZE='1'><B>Passengers squeeze more items into a suitcase before check-in due to enhanced security checks at Narita airport Friday. </B> KYODO PHOTO</FONT></TD> </TR> <TABLE> </PHOTO> <PARAGRAPH>People traveling during the peak of the summer vacation season were inconvenienced by reinforced security checks at airports, but carriers were operating on schedule, with no flight cancellations or delays.</PARAGRAPH> <PARAGRAPH>Japan Airlines Corp., which has two daily flights to London, said about 220 passengers left on a flight to London from Narita airport, while the plane from Kansai airport departed with roughly 240 passengers.</PARAGRAPH> <PARAGRAPH>JAL spokesman Yoshiteru Suzuki said the carrier had few cancellations for flights departing Saturday and onward.

terrorist attacks, the successful halt to the terrorist plot has had (little impact) on the public's attitude."

All Nippon Airways Co., which has seven flights a week between Tokyo and London, also saw no effects from the incident. Its Friday flight to London was almost fully booked, at 260 passengers.

However, ANA said it has stopped using its automatic check-in machines in an effort to increase security. The airline is asking travelers to arrive at the airport early, as it takes more time to go through the security checks, the carrier said.

Britain announced Thursday that police and the MI5 intelligence agency had arrested 21 people linked to a thwarted terrorist plot to blow up several aircraft midflight between Britain and the United States.
