I recently flew with DS, so I didn't need to pump. But my sister chatted up a women who was flying and pumping at BWI airport (Baltimore). In that whole airport the only bathroom with an outlet was the family bathroom in terminal B (I think that's the terminal we were in).
I don't remember the new legislation saying anything about places like airports supporting BFing or pumping.
Hi Jenny, I don't know if you've traveled yet, but I heard of another pumping option.
A women I spoke with said the Atlanta airport was very unfriendly for pumping (based on restrooms with outlets), but information suggested that she try the airport clinic. She reported that the nurses in the clinic were very friendly and let her use an exam room for pumping and it worked out great for her.
