I'm a frequent traveler on UA's DEN-STL route, and I've recently noticed that instead of having 3 737s a day on the route they are moving to 2 by late Winter/early Spring and only 1 shortly thereafter. Most of the replacements are either CR7s or ER4s which are considerably smaller than the 733s and 735s. Does anyone know why this is happening? The current flights almost always seem to be full and they are even keeping 3 737 flights on the return leg (STL-DEN). There is even a 757 scheduled for certain Sunday flights to DEN in January - is this for ski season?!
As a Premier Exec I'm a little disappointed at the overall downgrade on my most frequent flight...but that's life! Hopeing somebody could shed some light on these changes for me!
