(Est. 1994) “Frontier Airlines is an owned subsidiary of Indigo Partners. Currently in our 20th year of operations, we employ more than 3,800 aviation professionals and operate more than 350 daily flights from our hub at Denver International Airport. We offer routes to more than 75 destinations in the United States, Mexico, Costa Rica, Jamaica, and the Dominican Republic.”

I don't think you will get many complaints from going back to a Saul Bass-designed monogram — see first image below — but even without that knowledge, the update is an evident improvement. From the dowdy typography of the previous logo, Frontier has gone with a more active italic wordmark that properly integrates the old Saul Bass "F". It's not ideal, but it works. The livery is okay, nothing great, nothing horrible. The popular animals on the tail remain.
Thanks to John J. Custer for the tip.
