 What time is the right time to arrive at the airport this busy holiday weekend? CBS's Deborah Rodriguez takes a look. Travel experts tell the Wall Street Journal people with carry-on bags only can shave off about 30 minutes. Same if you download your boarding pass ahead of time. Subtract 20 minutes for TSA pre-check. Clear and premium fares. But if you're flying out of a major airport or parking or dropping off a rental car, add 20. Traveling with kids? Tack on an hour. This is CBS News.
