A lot of folks are curious how the two Icelandic carriers are doing at DFW. We now have three full months of data for them; worth noting as well that Icelandair is sending 183-seat 752s while Wow sends 345-seat A330s. Let's go June, July, August for overall load factors:
Icelandair - 71.99%, 79.51%, 69.48%.
Wow - 80.3%, 91.29%, 90.3%
How did we arrive at the data?
I took publicly available seat counts and other published data showing available data and came up with these estimates. I do not guarantee 100% accuracy, but I think we are fairly close to the true numbers. OAG, Various Source websites, airline sites etc.
