Alaska's EQM earning chart indicates that AA flights that are Alaska marketed and have an AS flight number earn according to the Alaska earning chart. Great!

But how do you actually book those flights? For example checking Alaska's schedule, they list 3 acceptable flights between LGA and CLE per week (why only on Tuesdays? Why only these flights? 🤷‍♂️)




But it doesn't seem like they actually will sell them, if we try to look up a routing between those airports on a Tuesday, nothing comes back.


So under what conditions will they actually sell these codeshares?
