All great ideas. A few more we (mostly I) do:
1. Pack food for the flight. Make sandwiches (without mayo) and pack them in softsided cooler (Can no longer pack blue packs

to keep cold) DON'T LEAVE THEM ON COUNTER FOR Brother-in-law to have for next few days lunch-you only do this once!

Add chips, crackers, cookies, and/or candy. We have at least 5 hours in the air. Usually we have more like 8 hours with connections, etc. We get hungry, and bored!
2.Check in online 24 hours before flight. I try to do this right at the 24 hr. mark. Print out boarding passes. Put in folder I keep all my important info in (WDW reservation info, car rental confirmation, any other confirmations, etc.) I keep this folder in my carry-on so it's handy at all times. I also put the stubs from the luggage tags in this folder.
3. Make sure all bags, inc. carry ons, have my name and phone number inside in case lost (This was invaluable last Sept. when I left my camera bag (without camera but with extra batteries and SD cards) under my seat-Delta found it and returned it to me, at home

)
4. Change my message on my home business phone. Of course, I don't change the house recorder-don't want those clever burglars to know that we'll be gone.
5. Double check carry-ons have no items not allowed on planes.
6. Make 2 photocopies of any, and all, credit cards, etc. that I'll be bringing on trip. Write phone number of cc co. on copy in case I need to contact them while away from home. Leave one copy at home and bring other copy with me (don't carry in purse, carry on in another carryon)
7. Make copies of any unused WDW tix I'm bringing. Also bring one copy with me and leave one set at home.
8. Make sure to bring any health insurance cards, just in case.
Most of my tips are for "just in case" cases. Hopefully you won't need to use your copies, or health cards, but it never hurts to be prepared.
