Found this in my inbox this week; info about the extra legroom is at the bottom. Interesting other changes precede it.

Dear SteveinSTL,
Soon you'll see the first tangible signs of our new partnership with Midwest Airlines, also part of the Republic Airways Holdings family. Although our family ties are new, our common commitment to the highest-quality customer service is not. Regardless of which aircraft you board, you’ll find a safe, reliable, comfortable flight experience.
Policy Changes Coming Soon
As we align our policies to support our integration, the following changes will go into effect on November 3, 2009:
• Beginning November 3, 2009, Midwest Airlines will recognize some benefits of EarlyReturns Ascent and Summit members. This means that Frontier’s elite members (with the presentation of their membership card) will receive two free checked bags and priority check in/boarding no matter which airline they book or fly with.
• Award ticket changes and redeposit fees will be reduced from $75 to $50 for redemptions on or after November 3, 2009.
• Standard award tickets redeemed on or after November 3, 2009 will be charged $20 for one checked bag and $30 for a second checked bag. View our baggage policy. CHOICE redemptions, Ascent members, and Summit members will continue to receive two free checked bags.
Introducing STRETCH Seating
STRETCH is the first four rows of seating that provide an additional five inches of legroom — that’s a minimum of 36 inches of comfy seat pitch in which to relax and enjoy the Frontier flying experience.
STRETCH will be available on select E190 aircraft beginning November 3, 2009 and will be expanded to our Airbus fleet by February 1, 2010.

Stay tuned for more exciting changes coming your way as we continue to integrate with our new family.
