My wife and I traveled with only our small carry-ons spending the least amount on our tickets. We were seated together on the back of the plane on a very full flight. We were both felt the cabin was a little too warm.
The flight attendants were polite in explaining numerous times all food and drinks were only available for credit card purchases.
When we checked in for our return flight on a flight only 70% full, I asked the counter person if possible we would like any seat that had extra legroom and to our surprise when we boarded the plan we found that we had exit row seats at no upcharge. Again the flight crew was very nice.
