Very unfair. Breastfeeding is not a good enough reason to have someone move. There are very discreet ways of doing this and if the mom was uncomfortable, that was her problem.

Yes - feeding in a lav is not a good idea. Even though this would not mean anything in this situation, businesses that are required to have a place for breastfeeding women are not allowed to use a lavatory for that purpose - for hygiene purposes.

Not sure why everyone thinks the husband made the flight arrangements.....it could have been the woman and she just wasn't able to get the seats together or didn't plan far enough in advance.
