Fortunately I am wearing good
hiking boots, so I don't have to stop all the
time to
empty my shoes, like the people who wear sneakers.
Since summer is always an expensive
time to fly — many routes, particularly cross-country fares, cost three
times as much in summer as the lowest base fare — with Virgin points, I had to hit the sweet spot between airlines trying to fill last - minute
empty seats and the day - of price
hike for truly stuck travelers.
