I'm at LHR and waiting to return. (We thankfully decided to stick it out and go ahead with the trip.)
But, LOL our flight back is already delayed since the plane is coming in from ORD. Yup, it's AA46.
If we are delayed by 3 hours we are due compensation. I have a feeling we will push off around 2hr 40min. Sigh.
This is reason enough not to fly AA to LHR anymore.
