How do you pump in an airplane? What are the rules?

In general, it should be okay to pump or breastfeed on your flight. Call up the airlines you're flying with to double confirm. Since you'll be in a metal tube for a good amount of time with strangers, best to take special precautions to be discreet in case a fellow passenger might complain about feeling uncomfortable. What one of my mommy friends would do is that she will tell the flight attendant in her zone as well as the passengers in her row about her intention to pump sometime during the flight. This way, if there are any issues, the crew will be able to reseat passengers. She usually pumps under a blanket and tries to do it before meal service or before the lights are dimmed. I know some moms who pump in the plane bathroom because they prefer privacy but if you do so, remember not to use the water from the taps because those are not clean. Ready a bottle of drinking water or request hot water from the crew if you need to sterilize equipments. Clease your hands with sanitizer. As pumps are usually electric in nature, best to avoid expressing milk before take off and landing sd they need to be turned ofg just like other mobile or electronic devices.
