And PUSH the airlines. It is not your job as a paying customer to be flexible and offer renting a car or taking a train as a solution. You paid to get from wherever to your intended destination. If they can't get you there, ask to be booked on another airline, connect through a different hub, a different time, etc. Renting a car, taking a bus or a train is the absolute last resort in my book. If I ended up having to do that, I would ask for a refund (to cover the cost of renting a car, Uber, whatever) or submit those expenses for reimbursement.
