having just seen this - brought back the memory the time we attempted to walk from T7 to T8.

Didn't have a clue and got the airtrain in the end as we were running out of time.

Is there something obvious we missed ? Like a walkway or signs to look out for ? Or maybe there is a walking guide around JFK somewhere ?

I know someone once wrote up about 'running' at airports but cant locate that now.

It would be useful to know in any case just in case the airtrain stops again.
