Thank you Rove312! I am finding the FT community is remarkably generous and savvy. Thank you for sharing the board's FAQ and ways to check on the daily flight path. I did check into it.... exactly as you sleuthed it from DEN to MKE to MSY. (And I get that there are probably one or two morning legs under a different number.) This advice really helps... at least I can get a sense late morning on how the flight is matching up iwith its on-time performance. And if there's a significant delay look into getting booked on one of the flights that routes via St. Louis or Chicago.
I feel like even though there are some things outside my control - at least I have a plan... thanks to you and InkUnderNails!
