i just booked an impromtu trip using Delta Skymiles for this coming weekend and was shocked and upset to see they are charging me a fee of $100 per ticket since I am booking only a week out. This costs them no additional money (ie labor) than if I booked it 3 weeks or more out. I am probably actually doing them a favor but they simply take advantage b/c they can. I used to love Delta (mosly b/c of Song when it existed) but have had some challenges with them over the past few years so I am ready to move on. Luckily, this has burned through the last of my Delta Skymiles so I will now try United & Continential to see if they are any better.
