Help! Trying to find a way home to DFW.

I am arriving at IAD on AF at 4:10pm on Aug 26.

I had originally booked a direct IAD-DFW departing at 7pm. Flight was cancelled and they put me on a 5:30pm flight. I decided this resulted in a transfer time that was too short... And rebooked a Delta flight IAD-ATL-DFW departing at 7:50pm. The IAD-ATL flight was cancelled, and the new IAD-ATL flight departs at 5pm. Again, this flight won't work and I decided to cancel it

There are now no good options.... Which one of these do you think is the best chance of success? I'm flying in the front of the plane on arrival, will have GE and TSA pre check, and will be carrying on, no checked bags.

1) 5:30pm IAD-DFW flight. Leaving me with a 60-70 min intentional to domestic transfer
2) 8:10pm IAD-CLT-DFW flight, with only 37 min transfer in CLT
3) 7:30pm DCA-DFW, with 3 hr transfer to get from IAD to DCA, and through security

What are they chances they add a flight that will work for me? Probably none right? So, I have to choose one of the 3 options above.

I'm leaving towards #2. Any delays for my incoming flights is okay, and just have to make the 37min transfer at CLT work. Ask flight attendant to help get me off the plane first, and ask gate agent to notify CLT-DFW agent that I'm on my way? Option 2 get me home at the latest time though. I looked up ontime history for IAD-CLT, and this seems like it's late a lot... So, maybe not.

Now, I'm thinking the 7:30pm DCA-DFW is better. There's a 8:45pm DCA-DAL on Southwest that might be better too

Thanks
