Fact is if you're travelling and it's feed time, you have no choice. Not to mention it's actually recommended at take-off and landing.
I've BFed on long-haul BA flights, short haul AA flights in the States, and once on an Air France flight, stuck next to a random guy- I tried my best to keep it as unobstrusive as possible.
And of departure gates etc. And the Eurostar (yes, I have a well- travelled baby!).
I've never had any comments whatsoever. At takeoff and landing, I put the safety strap around DD and that was it.
I resent comments like the 1st from the article you posted. 'I BFed my children, but I still don't want to see someone boob and a baby sucking, it's private etc etc etc.'
It's not private, it's food. What are you expected to do, not travel? Or let your baby go hungry?
You're not nursing for show on an airplane, you're nursing because it's feed time. Not to mention there's nothing to see, even if you're sitting next to a BFing mother- unless of course you're staring!
