I was allowed two 50lbs bags
If you mean "my ticket said '2x50 bags included' already in advance", then I'm surprised. But if you mean "I brought two 50 pound bags with me to the airport, and they didn't say anything", then that means absolutely nothing - first of all, most airlines are not
m'dakdek k'chutas sa'areh; second of all, many check-in agents are so used to 50 lbs. from other airlines, that they don't even bother checking the fine print where it says 44. (Or they assume it's inaccurate, or simply don't care.)
