Was visiting UK in late January, and took a side trip to Rome on
EasyJet (leaving from Stansted airport)

Morning flight from Standsted to Rome leaves early (8am), so I got one
of the earliest trains (5:30AM) out of Liverpool St station for what
should have been a 45 minute journey (ETA Stansted 6:16AM).

This would have left me more then enough time to check in and get
through security for the 8AM flight. As it turned out, my first
experience with this service was an express ride to a missed flight.

We left Liverpool station at the appointed time (5:30AM), but had
lengthy delays at a few points on route. This "express" train arrived
1.5 hours late into Stansted airport at 7:45AM. By the time I got to
the checkin counter, the airline informed me that checkin had closed
some 30 minutes ago.

During this "express" journey, there was no effort from any of the
train crew to inform dozens of very anxious passengers about the
reasons for the delay, or if SE were going to quickly come up with
alternatives.

I took pity on the Express train's Customer Service Agent at Stansted
airport having to deal with a lineup of furious passengers, (she was
very good at telling everyone about how the problem was not their
fault) as well as airline CSR's attempting to rebook a mass of irate
people on future flights.

Lost a day on my Rome Vacation, and to be honest, I am greatful to
have made it to Rome at all.

A word of advice: If you must be at Stansted for an early morning
flight, do yourself a favor and take one of the bus services that are
available, or if you can afford it, a taxi cab. (FYI - cab fare from
London to Stansted can cost more then the airline ticket)

First and last time with this express service. Better luck to
everyone else if you decide to risk using them.
