I thought I had the explanation, but it is not so simple: aa.com schedules do not show the 80 min connection LHR-DFW-HOU in June.

I am not sure how to interpret the repetitive lines on the KVS display, but towards the bottom it has:

AA W 05APR11 --- --- 085

If that line overrides the others, I interpret it as:

AA Wide body is 85 minutes from 5 April?
