Just noticing that American is making a weather waiver available to those flying out in the next couple of days "who can fly from March 17-21st?" I seem to remember you could push your flight back months later if you could not get out on the day the airline contracted you to fly. This looks like an extremely short and unfairly small window in which to travel? Can anyone clarify. It's especially distressing because these days if you are cancelled on the 17th, the next flight might not be until the 20th or 21st.
