We flew to Manchester from Orlando International. When we tried to reach our gate lines for security were 4 to 5 wide then merged very slowly into 1 line. People that choose either of the outer lines appeared to jump into the middle of the line as it merged. All in all the simple bag and clothing checks were over 1 hour on the day we flew. The whole process was a disaster we could see that Homeland Security people were trying their best but appeared overwhelmed by the situation. Other aspects of the airport are fine road access check-in facilities for eating etc.
