With Delta's agreements, ZED on VS and AF is hilariously cheap! Wishing for first/business class is just greedy, I guess. But I do not repent.
We're looking at going back to Zambia again and I'm scouting alternate routes and carriers. That's how this came up.
Does anybody use FlightStats to check carriers on specific routes - it's a great resource. It has limits on future outlook - usually only 3 or 4 days, but it gives you a snapshot that you can verify on a scheduling website (carrier, Kayak, etc.).

Thanks for the intel. FOMTS (Father Of My Three Sons)
