London is a failure. And I'm not kidding. WHY do they not have ANY idea how to deal with 4 inches of snow??? My plane was supposed to get in 1/2 hour early - as it turned out, we got in 1/2 an hour late and then sat in the runway for 3 hours while they waited for clearance to go to a different terminal. Then EVERY short-haul flight from London was cancelled so I waited 5 hours in line to rebook my flight. Cross your fingers that my 7:30 flight tomorrow actually takes off.
