My wife and I were planning to fly IAD-TYS last Friday. We were originally offered $600 each but one of us would be on the later flight and then other on a flight the next day. I passed and was offered $800 per passenger if we opted to fly to CHA instead of TYS. We would still fly back to IAD from TYS for the return. I quickly checked Kayak on my smartphone and locked into a 1-way CHA-TYS Alamo rental for $21 and took the offer. Without asking, the agent also gave us two $10 food vouchers which we used after we returned the rental car at TYS.
The CHA flight was waiting for us so the door closed right behind us and we got to enjoy the luxury of the very last row on a CRJ-200. Less than 2 hours after we landed in CHA, we returned the rental car at TYS and got on with our day. Not too shabby for $1,600 worth of vouchers and a free visit to Starbucks.
