A smoke hood would be good to have, for both the flight and the hotel stay. Coupled with a small, bright flashlight, those two should let you safely evacuate either location in a timely fashion. A smoke hood that filters carbon monoxide would be best, but even one with an activated charcoal filter and a hood that protects your head from heat and flames is much better than nothing, and they usually store much more compactly than any hood capable of filtering CO. Brookdale's EVACpac is a nice combo.

Some sort of auxillary power for your cell phone, in case of extended stays at the airport or being put on hold for a long time to rebook a cancelled flight would be prudent. Someone recently posted a message on the Cellboost. The Charge2Go! would be another option.

Depending on how you dress on the plane, some warm clothing. Some cabins are colder than others and there aren't enough blankets. And your checked luggage might not make it, and you need to get to your hotel in winter weather.

Earplugs. Airports, airplanes, and hotels can be noisy places. Excess noise is distracting and gets on our nerves, hours of plane drone is tiring, and we all need our sleep. I love babies, but not screaming babies on airplanes. And what's with the love fest in the hotel room next to me? <img src="/images/graemlins/wink.gif" alt="" />

Headache medicine. I think it's the altitude that does it since I try to fly fully hydrated and drink lots of water on the flight. Cabins are only pressurized to what, 6,000 feet? If I have a headache, then I'm cranky and can't sleep well on the plane and the flight seems soooo long.
