 I'm Peter Greenberg, and this is today's ION Travel Minute. More Americans are traveling than ever before. Planes and hotels are full, and on balance, airline tickets are very expensive, as well as those hotel rooms. But can this be sustained? In April, 38% of Americans surveyed said they were willing to go into debt to support their travel. And then the bills came due. And at the same time, many banks are now reporting credit card delinquencies are on the rise. In the short term, airfares and many hotel room rates are now starting to come down, beginning in August.
