A few changes that I'd like to see:
1) Discounted rate at MKE Best Care Club - I used this club for the first time last month on a free pass that I got when I reached Executive status. The club was nice but virtually empty. There were only about 5 other people while I was there. The day rate is $35 for up to two people. I travel solo and $35 is too much when I only have 60 to 90 minutes at the airport. A reduced price for elites and/or solo travelers might bring a few more people into the club. I might be willing to pay $20 to get away from the crowds for a short time, but no more.
2) Waive the standby fee for both elite levels. You could still prioritize Executive over Ascent. I've never understood why airlines don't want to encourage people to take an earlier flight when they arrive at an airport early and the earlier flight is not full. It makes people happy to get home early; it is good customer relations that costs the airline nothing. A couple of years ago, Midwest would routinely let you on the earlier flight at no extra charge but unfortunately this changed after they were bought by Republic.
3) I also like the idea of a little extra time to reach elite level if you are close at end of year. I recall last year I got an email from Midwest stating they would give until Jan or Feb to earn segments necessary for Executive status. As it turned out, I had enough segments at the end of December; however, this year, if my travel goes as scheduled I will only have 28 segments by year end. It would be nice to get a slight grace period so I could be bumped up to the next level.
4) I'd also like to see an alliance with an international carrier.
