I live in Columbus and take these "commuter" type flights on Delta all the time for business trips. Seems as though most of the Delta flights originating at CMH are on these smaller "commuter" type planes. As a general rule they are not bad flights as long as they are not completely full. The planes are small, the aisles are small and it seems to me that the seats themselves are smaller, so when the plane is full it is really

!
As far as luggage goes, I'd plan to gate check anything larger than a handbag or laptop. The overheads are really small and it is a stuggle to get even a small suitcase in the tight space. Most of the time on the commuter flights they will request that you gate check anything larger than a purse or a laptop anyway (including stroller), especially if the flight is full or even close full. To gate check your bags- you just leave them on the tarmack with an agent who gives you a baggage tag then, they will wait a few minutes to allow everyone to de-plane, but when you are allowed to de-plane your bags are waiting for you on the tarmack. No need to go to baggage claim to retrieve them this way, just pick them up on your way off the plane and your all set. If they do not request that you gate check your bags, I don't know that you could get a suitcase over 19" or so in the overheads or even under the seats (unless your really good at stuffing sausage

).
Another thing to keep in mind, if you check your bags when you check in at the airport. If the plane is full (or close to full) they may send your luggage on another/later flight due to weight considerations on your flight. In the words of a Delta agent "they would rather get people to the destination and send bags later." I have had this happen a couple of times. The worst was this Christmas when DD and I took a trip to ATL, we check 3 bags and they arrived in ATL on 3 different flights at 3 different times

! My theory up to this point when I fly on a smaller plane was to check all of my bags since I'd have to gate check them anyway, plus this way there is no need have to lug them through security and then through the airport. However... after our Dec trip I think I'll be gate checking bags for now on and hopefully avoiding the 3 hours at the airport collecting baggage after the flight arrives

.
Oh, and by the way it is not possible to get frequent flier miles for your bags...I asked, figured if my bags came on three different flights I should get the mileage for three flights. The agent thought I was a nut...

but she did give me three $50 gift Delta certificates, so I can't complain to much.
