KVS Availability Tool vs. ExpertFlyer
I am trying to decide which of these services I should join. I do mostly international travel on UA and of course am looking for bargain C and Y class fares, upgrade opportunities from Y to C inventories, and UA award information. Do you have a preference after (hopefully) your personal experience with both? Which would you choose today?
Thanks in advance for any comparasion you can offer and any suggestions you might share.
