I'm embarrassed to admit this, but I have been checking my bag every time I take a weekend plane trip. This week, however, I ran the numbers. Delta charges $46 round-trip to check a bag online, $50 at the airport. That means buying a top-quality, $200 carry-on bag, as expensive as it seems, will pay off in about four trips. Thus began my search for carry-on luggage. And no matter how much or how little you travel, there's a carry-on bag that's right for you. A sampling: The infrequent flier The cheapest rolling bag I could find was the Personalized Rolling Pilot Case from Walmart for $28.74. Intended to be a substitute for a book bag, this option is not sturdy enough for frequent travelers. But it does have a retractable handle, wheels, and will fit into overhead compartments. If you only fly one to two times a year, this overnighter, complete with a 60-day warranty, could do the job. The occasional explorer Samsonite luggage is known for dependability, and the prices are a bargain for someone who travels every two months or more. A Samsonite Aspire GRT carry-on will run you about $89.99 on sale from Samsonite.com. For $107.99 you will get the same model with spinner wheels for better maneuverability. If you choose Samsonite, comparison-shop on its website and at stores; you may find better deals online. The veteran jet setter If you're a seasoned traveler who flies once a month or more, consider Briggs & Riley luggage. This company guarantees its luggage for life — even if it's damaged by the airline. A Briggs & Riley carry-on will cost between $209.25 for the 19-inch International Upright to $449 for the 20-inch Carry On Business Upright. The bottom line: You won't have to buy luggage ever again.
