Probably using a hand pump or battery operated one while you are traveling would be the best. What pump are you currently using? I found that a hand pump was the hardest and that I woudn't have enough milk - maybe 4 oz?
Try contacting a la leche league near you and I'm sure they can give you a wealth of info. Here is their web site:

And my favorite site for nursing moms - the boards there will be able to help you too...
