Travel documents I carry with me internationally

A copy of your "Yellow Card" showing which immunizations you've had and when.

That's a lot of paper to cart around on complex itins.

I don't worry about printouts of lounge rules and elite benefits. For flight reference numbers, seating, u/g requests etc I have a table that generally fits on one page unless the trip is especially long (more than 30 flights). For hotels I printout out the address info if it is in a strange city, especially if I don't speak the language well. Also the hotel confirmation for non-chain hotels.

If you're going to a country that requires a visa, you should bring a photocopy of that as well.

Also, I try to leave a copy of my passport information page with someone back home, in case my passport, laptop, and the copies I brought all get lost/stolen (which can certainly happen). They can easily fax it to my hotel.

Also if you're renting a car, you should have that confirmation and any applicable coupons. If driving a long distance print out directions and always check the rental rate on the contract (it has come up higher a few times for me). The last thing I check on a rental car before pulling out of the lot is to look at the gas guage to see if the tank registers full. Sometimes it isn't.

The customer service numbers and info for any credit/debit cards you're carrying, just in case your wallet gets lost/stolen. If you have a trusted friend or family member back at home, this is a good list to leave with them as well so you don't have to spend quite as much time on the phone paying international rates cancelling everything...

(I have firsthand experience that this is a very good thing to do, alas.)

I carry too many photocopies also. Just anal, I guess. I add a couple of passport photos. And I scan and email to myself all travel docs (including copies of the front and BACK of credit/ATM cards -- for the customer service phone numbers), so they can be accessed from any computer. Especially copies of your passport, visas, PIN numbers (coded some way, for security), etc.

I would scan and email key documents (passport visa etc) to a web based email account so you have access in case of issues 🙂

When traveling to various asian countries (not being a speaker or writer of any asian dialect) - I have a local contact write the name/address of hotel and office (or other destinations) in the local language to hand to the cab driver.

Not having these has resulted in some interesting wandering trips (in Japan in particular).

Lucky, did you know you can do most of this on www.tripit.com, and avoid carrying around all of that paper?
