Although I have not pumped while on a flight, I do understand the need to pump even in an uncomfortable or awkward situation. My thoughts are these-- maybe dicuss this with the flight attendant when you get on board so he/she knows you have this need. Do you know if the flight is booked? If not, try to request to sit where the seat next to you is not occupied. That way you'll have more room. Is your pump charge-able or battery operated? Mine was, which helped when I needed to pump somewhere that I could not plug it in... This may sound strange, but scope out the other people on the flight and try to "find" another mom who you can assume has gone through this in one way or another. Someone like that would be easier to sit next to while pumping, ya know? If you do find someone like that, see if you can switch seats. Good luck to you!!! I hope it goes well and that you have a good trip!
