I also experienced recently that gate agents will lie about this to decrease turn around time if a plane is running late. We were forced to gate check ours after being told the plane was too full to hold all, only to get onboard and find ample space. When we asked the flight attendant, they apologized and said they did not tell them to do this, but it’s unfortunately common at airports with frequent delays. So charge ridiculous bag fees, forcing everyone to carry on, which delays boarding, so they lie to you and check your bag for free (which maybe you would’ve done to begin with if that was an option), only to board a plane and feel duped. All around great experience!
