What are add-ons and end-on-end combos???
 

I found an I fare (discount business) on AA to London that permits add-ons and end-on-end combinations. Problem is I have no idea what these are. Would someone be so kind as to explain? Is it unusual for the fare rules to allow them?

Got it....Thanks.
 

Thanks, KVS.

Got the end-on-end. Don't know why I didn't find that site in the google search I did.

The link didn't have a definition for "add-on" but I now realize that the "add-on" is the "proportional fare" for the leg to the gateway fare (ex: SFO-ORD for the gateway fare ORD-LHR).
