Unable 2 eat anything but liquids due 2 nausea 4 about 2 days. i'm supposed 2 get on a 5 hr flight from dc-ca on 12/25. should i reconsider traveling?

Not necessarily: As long as you can keep food and liquids down you should be fine. I would advise you to take a pregnancy test if you have not done so if there any change you might be pregnant.

Don't fly when ill: It's not good sense to fly to a new environment where you might not know anyone. Get to you family physician asap. Any thing could be the cause including pregnancy. It's not a good idea to be so nauseated in an airplane.
