Miss calculated schedule timing on the Northern line tube on an early Sunday morning UA LHR EWR got on a later flight.
Had a similar one LHR-YYZ-EWR
we took the tube and 3 stops before LHR they announce that due to morning rush hour everyone get off and wait for the next train since they are turning this one around...WTF! and the next train to pass was too full to get on.....
We still arrived at the airport more then 60minutes before but waited on the wrong line, got to the right line at 59 minutes and they said sorry, we'll rebook you on the next flight..... for $100 a ticket... (*5) ......
Then the flight was delayed in YYZ and when we got on we just taxied to nowhere, because YYZ doesn;t want us and EWR cant take us..... OH but drinks were free....
