The ladies were well taken care of in LGA.
They were met at the curb ready to check the luggage, taken through security without any hassle. The mother-in-law thought the AC club was the greatest thing. They were the first on the plane, then back home.
It's an expensive service but did make the travel experience hassle free for my wife.
Well worth the money.
Thanks to the posters on this thread for the information, they were more helpful than 2 of the 5* agents I spoke to.
