I want to apprise you of new security restrictions at London Heathrow Airport.
When you are transiting, even from the same terminal (ie Terminal 3 to Terminal 3) you have to go through a full security check in again. You will have to allow almost 2 hours to do so. No more running from one place to another. If you are transitting to Terminal 1, 2 or 4, you go to the bus and you have to go through the same routine when you arrive at your designated terminal.
It is mass confusion as they implemented a procedure with no forethought or organization. (what a surprise!)
When you deplane, you are to go to a special line where you wait for more than an hour. No one is there to instruct or advise you. There is no signage, and the wait is interminable. When you finally arrive at the security gate, you are advised that you will only be able to carry on 1 piece of luggage (women, a handbag is your only carry on, and if you have another piece , you must consolidate.) People were panicked, and if you cannot consolidate, you will have to select which to bring on and then check in the additional piece. There are no tables to put your bags upon, no chairs, and no organization.
My client told me that there were people crying and asking for help as they missed their connecting flights. This nightmare is just in time for peak summer travel, and if you are going over, you MUST allocate enough time or else flights will be missed.
