I flew on AC 311 last night and had a bit of a frustrating experience. The passenger next to me was using an inflatable footrest (basically a giant blow up pillow) which fits between the back of the seat in front and bottom of one's own seat. That is, it completely fills the space where your feet would normally go. It's not a piece of luggage, it doesn't store anything, and is purely for personal comfort. The passenger brought it on the plane fully inflated (in addition to 2 bags) and had it at her feet from boarding through taxi and takeoff. Two AC FAs including the SD looked at it during the pre-flight seatbelt checks and didn't say anything.
What's the point of all the safety announcements and informational videos if FAs don't actually enforce the rules?
