Looking at "manage my booking" on the BMI site... I was trying to work out why a journey between London and Marrakech would take 2 hours 35 minutes in one direction but 4 hours and 35 minutes in the other.

Rejecting the theory that it's harder for planes to fly up the globe than down, I'm leaning towards the thought that BMI doesn't understand that LHR is an hour ahead of Marrakech for most of October and both cities are GMT+0 in November.

Outbound: London Heathrow (LHR) to Marrakech Menara (RAK)
XX October 2011
Depart XX Oct 2011 10:05 LHR
Arrive XX Oct 2011 12:40 RAK
Duration 02:35h

Return: Marrakech Menara (RAK) to London Heathrow (LHR)
XX November 2011
Depart XX Nov 2011 15:40 RAK
Arrive XX Nov 2011 19:15 LHR
Duration 04:35h

The journey time in either direction is 3 hours 35 minutes ... right?

Mods: Feel free to move this to a thread for BMI website burps. I couldn't find one, though I'm sure I've seen one before.
