I just found out that I will be traveling to Russia for work for 8 days. I BF DD / pumping while I'm at work. Has anyone taking a very far away trip without LO and have any general pumping tips? I'm concerned about keeping my supply up. I'm not planning to keep the milk - the logistics will just been nearly impossibly. Plan is to pump & dump (as painful as that will be! That's a lot of milk to lose!!), with possibility of keeping milk I pump in the last day or two. I have enough freezer supply to last most of the week and DH will just supplement with formula when necessary.
My questions are:
1. Has anyone been on a long plane flight where you have needed to pump multiple times? How in the heck did you do this?
2. I use the Medela Pump InStyle. That would be quite a bit to lug around, especially since I'm not planning to keep most of the milk. Do you think a manual hand pump could get the job done?
Thanks for any advice. I'm excited for the trip, but dreading leaving DD for that long. Thank goodness for Skype! 
Re: Traveling to Russia for work - Pumping ?s
Wow! No, I have only done one little flight so far. Planning for a longer one next month, but not internationally yet.
Research your flight to see what your options are for electricity in your seat. They probably won't love you taking up a bathroom for 10-15 minutes.
A manual pump will be useful even if you don't use it that much. It can at least relieve engorgement, you can use it in the bathroom or in your seat. I have a single electric that runs on batteries and do not recommend that. It's terrible. I'd personally still bring your PIS - you'll be more efficient and it'll be a relief. I also feel like you'll keep up your supply better. Don't forget the plug adaptor you'll need for Russia.
I'm a little shy to post this, but I wrote about my recent flight on our very neglected blog. Maybe some of what I did for prep will help you? Definitely report back on how this goes for you. Good luck!

Do you know if you will be able to plug your pump in, given the different voltage? I know there are adapters for this sort of thing, but when I traveled to Eastern Europe during college, I brought an adapter for my blow dryer, but it burned up the first time I plugged it in. Maybe I screwed something up, and it was just a cheapy blow dryer, so no big deal. But I'd hate for that to happen to an expensive pump.
This is the main reason I was thinking of the manual pump.
