As you can see from the above (here is the link to the page at Delta.com) you can get free changes if you are flying today or tomorrow in much of the Midwest. Finding space, however, will not be simple.
The winds in my home town of SBN are going to hit gusts of 50MPH+ and by tomorrow they are saying snow going sideways!
Today the rain, then followed by dropping temps and then ICE and then winter really arrives (why did I leave GCM)! So, sure you may have travel plans you don’t want to miss, but maybe it is better to be stuck where you are in a warm safe place over an airport full of frustrated travelers all of whom do not fly as much as you or me!
Be safe everyone – Rene
