I see all of these references to taking shoes off. I guess I've never paid attention: do you guys fly with shoes that easily slip on and off?

Mine just stay on my feet, unless it's a TPAC and I'm in J/F with the slip-on booties or something.

I have a small torch to hand,
Nothing to do with evacuating the aircraft though, It comes in very useful if and when
small items disappear into the under-seat darkness.

Another thing is that I have my flight details in a durable label firmly attached to my case, I've seen too many airline tags
get detached. No one in baggage handling is going to track someone by their destination address, not immediately at
least. Flight details give the luggage a better chance of being retagged and joining you on the aircraft.

For me it's the TPACs (her family is on the other side of the ocean). I don't actually remove them, just greatly loosen the laces.

When I sit down I do "take a moment to locate the emergency exits," as the US safety briefing asks. Those which aren't in locations that would be obvious to see in dim light/smoke, such as the fore and aft galleys, I count the rows to.

I keep my shoes on during takeoff and landing. I actually keep my shoes on most of the time. The main exception is overnight trips where I'd like to sleep and taking them off helps. I don't wait for 10,000 feet or anything like that, though. I figure one or two minutes after takeoff/before landing is enough. The point is to have them on within the window of time when, if an emergency occurred, I wouldn't have enough time to slip them on before having to get up and move.

I tend not to keep my passport on my body as it gets crumpled in any of my pockets, and wearing it on a lanyard around one's neck screams "Tourist!" I keep important documentation in my messenger bag, which I usually stow at my feet. If foot space is tight and there's enough bin space I may stow it overhead-- but not further away than arm's reach.

Wipe down armrests and tray with a disposable disinfectant wipe.

My flights are mostly ULH, and I always fly with slip-on shoes rather than lace-ups. Not only is this far more convenient when you need to get up during the flight, but it's also far easier at security checks where you may be required to remove your shoes. Some airports still don't provide seats after the security checks, so slip on shoes make things easier.

What's with those people who use the loo during flight just wearing their socks or barefoot?! That liquid on the floor ain't exactly holy water...

Doesn't anyone else assume the crash position when approaching touch-down ?

I keep my passport in the seat back pocket, wait until airborne to remove shoes (but not until seat belt sign is off, once we're careening through the air we're not about to evacuate either way) and put them on about 5 mins before landing, I wear my seat belt throughout the flight, as of about 3 or 4 years ago when there were increased reports of injuries over the South China Sea, and keep my feet flat and legs uncrossed during landing.

Note the direction to the nearest exit and count the rows.
Shoes on until cruising altitude. Back on when the descent begins.
Safety belt on when seated.
Passport and wallet on my person at all times.

Pretty much all of the above including removing my spectacles for take off and landing.

Most of the above.. take-off/final-approach seating is to be sitting on my hands (left hand under right leg and across [taken from often observed FA behaviour]).
For long-haul I'll do some FL300+ weather research (jetstream forecast) to have an idea how bad turbulence could be (able to sleep or not..).

Also I try to greet my seath neighbor with a friendly smile when boarding to frame a good start, if possible.
