I hope this isn't a tired subject..ZED fares!
I am going to travel JFKCAIJFK in FEB. I see that we have ZED agreements with several carriers. For example, JFKCDGCAI/AF, JFKAMMCAI/RJ,and JFKAMSCAI/KLM. These are ZH fares for me. Can I pick any entry point from JFK with the same ticket? Do I understand ZED fares are sort of generic? Is there a written explanation of how they work some where on GOZED or elsewhere? I would like to prevent purchasing a ton of back-ups. Can anyone help? Thanks
