Was on the 920 from STR last night, after the standard announcement for preparing for landing, we were treated to an all-singing, all-dancing 'how to' video highlighting the various options for transferring at T5. Over the course of six or seven minutes, the video runs through the procedures for the main types of transfer, namely INT/INT, INT/.DOM, INT/T1-4 (no mention of using e-Gates however!

). I was beginning to think that this was a new 'enhancement', however the mention of T1 led me to think this was a legacy video that is no longer used. Having recently read this guide in preparation for a ex-SVG TP run over Easter, I couldn't help but think that the video had used this thread as a reference!
I only fly 20 or so SH segments a year, and don't recall seeing this video previously. I can speculate that the flight had plenty of onward connections that evening, and maybe the cabin crew thought it may have been of assistance? The plane was one of the newer 320s (G-EUYR), which had a more hi-res moving map than other birds in the fleet.
