FWIW, My random travel habits/tips:
1- If you're traveling to the US and know someone in the states, sign up for a Google Voice account - Free and doesn't expire. You can use the account for reservations, calling the states (works via wifi too!) and sending SMS etc. You can also sign up when you land if you have a US number they can call (activation requires them to call a US number with an access code.) I find my GVoice # super handy. You can also port an existing US # to the service.
2- When I get on flights, I have a small pouch with plane essentials that is in the front pocket of my backpack that I can quickly pull out when we board so I can get settled faster. Eye drops, fave eye cover, ear plugs, USB cable (never leave home without!), pain killers, sleeping pill, pen, saline nasal gel, etc are in there.
3- Everything else i need on flight - aka bulkier items - is in the main compartment in a plastic bag that I can easily throw away. Water bottle, kindle, Bose headphones, laptop adapter if needed, etc. I tend to leave in backpack at least past the gate so I don't get hassled by anyone for carrying on "another bag", but usually like to be hands free if it looks like the person in front of me might need some help
My goal is to get my bag stowed and put away as fast as possible and clear the aisle. I hate when people take 2-3 mins to take their seat upon arrival to their row. i consider it a personal failure if I take longer than 10 seconds for my b*tt to hit the seat.
4- I keep all my country specific currency, SIM cards, loyalty cards, adapters in labeled plastic bags in a drawer so I just grab a country bag when packing (US, Hong Kong, etc.) I tend to swap these things mid flight so when I land, I'm all set with currency, my travel credit cards, etc.
5- I keep shampoo/conditioner samples (I seem to always have these) in my travel toiletry bag for lounges w/o conditioner (pet peeve.)
6- As I always bring back the duty free limit of wine, I keep "wine diaper" bags (zip bags lined w/ diaper material) in my suitcase for easy wine storage. I've never had a wine bottle break (and the TSA sometimes rips the bags (grrr)) but I'm a bit paranoid when I see baggage handlers throw bags around.
Apologies if some are repeat. Didn't feel up to reading the entire thread yet
