UK Terror Alert
Due to the terrorist incidents over the Weekend, all the major Airports across the UK have increased their level of security. Delays are being advised.
Air passengers and rail commuters are to bear the brunt of heightened security following the three attempted bombings in London and Glasgow Airport.
Cars, including taxis, are being banned from approaching terminals at many airports, and vehicle searches at train stations are being increased.
Passengers are being urged to travel to airports on public transport or allow extra time if arriving by car.
Police said the increased presence would act as a "visible deterrent".
The UK moved to its highest level of terror alert - critical - after a Jeep Cherokee crashed into the doors of Glasgow Airport's main terminal and burst into flames on Saturday afternoon.
The incident came a day after two cars loaded with petrol, gas cylinders and nails were found in London's West End.
Today's travel situation:
* Traffic at Heathrow Airport "busy but moving" and no flight delays
* Glasgow Airport back to normal but delays and cancellations possible
* Congestion at Gatwick Airport from police checks on approach roads
* Stansted, Liverpool John Lennon, Southampton, Edinburgh and Aberdeen airports all reporting normal service
A number of airports have already taken extra security measures, including Heathrow, Edinburgh, Newcastle, Birmingham, Manchester and Blackpool.
BAA said access to forecourts and drop-off zones at terminals across the country would be "severely restricted".
A spokesman said people who usually drive up to entrances were being advised to use public transport or to use short-stay car parks.
