I'm normally an enthusiastic advocate of smart phone technology as an aid to travelers, but a recent glitch in iPhone software is giving me pause. Countless iPhone alarm clocks failed to go off on Sunday and Monday mornings, thwarting travelers' plans, as reported in the New York Times and the Wall Street Journal. According to the Times: "Erick Piller, a student who uses his iPhone as a primary alarm, said in an e-mail that he missed a scheduled flight [Monday] morning after Apple assured the media that the alarm would begin work again on Monday morning. 'I set a nonrepeating alarm for 3:30 a.m. Monday, but when I woke up by chance at 4 a.m., it hadn't gone off," Mr. Piller said. "I ended up missing a flight by 15 minutes." I, myself was a victim of snoozefest2011, and almost missed an early morning flight out of Palm Springs on Sunday morning. My husband had diligently set two iPhone alarms for 4:30am (a 3G and a 3GS), neither of which went off. (We randomly woke up at 5am, thanks to our toddler, and just barely made our flight.) I rushed to blame my poor husband, but the blame lies with Apple, which experienced a similar problem with iPhone 4 during Daylight Savings Time. Apparently, Apple is on the case, but bloggers around the globe were quick to devise workarounds. One quick solution, shared via Twitter (check the hashtag #iphonealarm), was to set a recurring alarm, as opposed to a one-off, non-repeating alert. That fix seemed to work for many—and as of this morning, reports are showing that alarms are again ringing—but for this particular technophile, I'm leaning toward regressing to old-school technology from now on: a trusty, old-school, properly ringing clock.

In the past week, thousands of flights were canceled at European airports because of uncommonly icy weather. In Germany, there is a word for what happened next: "Winterchaos." I witnessed some of the melodrama when I attempted to fly from England to the United States earlier this week. On Sunday at 5:30 in the morning, I arrived at Heathrow's airport. Officials were preventing passengers from entering the airport unless they were booked on a flight still scheduled to depart. Travelers on canceled flights—including some families with young children who hadn't dressed for this situation—had to stand in the dark and cold outside of the airport's entrances for at least an hour. Eventually, I flew to Dusseldorf and, from there, took a train to Frankfurt. The scene that greeted me at Frankfurt Airport was surreal. Lines of passengers stretched up and down the airport. A TV news crew followed one Lufthansa official as she talked to passengers standing in a particularly long line. She said it would take about six hours for these passengers to get to the front of the line and rebook their flights. She and an assistant then handed out free buttered pretzels, sandwiches, and bottles of water. Here are some lessons, which could be helpful in other airport crises: If your flight is canceled while you're at the airport, you should call the airline while standing in line waiting to be rebooked. Otherwise, you may have to wait for hours to reach the agents at the counter rebooking a whole plane. A telephone rep may instead be able to help you sooner. Cell phones overseas can't call U.S. toll free numbers for the airlines. Tip number one is to print out Budget Travel's wallet card with airline phone numbers (opens as a PDF). This includes local numbers, not just toll-free numbers, and you can dial these local numbers from overseas. If you've misplaced that card, what to do? A few years ago, to call an 800 number from abroad, you could replace the 800 with 880. But that's no longer allowed. Today, the best way to call domestic U.S. 800 numbers from abroad is to use AT&T; USADirect Service. Go to that website, pick the country you're visiting, and you'll see the phone number you need to dial. You must pay for the call because the 800 number is toll-free only in the U.S. Bill your credit card. Don't depend on the phone, though. In a crisis, many airline phone centers can't handle the number of calls from upset passengers. Last Monday, for instance, wait times for Continental Airlines's toll-free number surpassed half an hour. But many airlines and airports were getting out the word about cancelations and closings via Twitter. Wait! Keep reading! You don't have to use Twitter. Without signing up for the free service, you can still see relevant updates that have been posted online through it. For example, you could go to www.twitter.com/heathrowairport or www.twitter.com/lufthansa _USA to see the latest alerts. How do you find out the relevant information? Go to Google and search on "Twitter" and the name of your airline. Example: Twitter Delta gets you or www.twitter.com/deltaairlines. Airlines prioritize their long-haul flights, and you can use that fact to strategize. During a winter storm, you may be rebooked on a flight that is doomed to being canceled, too. One way to figure out the odds of whether one flight is more likely to be canceled than another is to check if it is a long-haul flight (across the ocean) or a short-haul flight (between Seattle and Denver). Long-haul flights are more likely to fly. Airlines would rather get their large, profitable planes in the air than their smaller planes, which carry fewer passengers, obviously. If an airport tells an airline, "We've only de-iced one of our runways, so you have to choose which of your two planes you want to fly out," the airline will pick its biggest plane flying the greatest distance—more often than not. So when a gate agent offers you a choice of rebooking options, you're usually better off picking the bigger plane going the farthest distance to an airline's hub airport. (There are exceptions, of course.) No planes flying out for days to your destination? Ask if you could fly to an alternate airport. If flights to your home airport are unavailable for days, you may be able to fly sooner to a different airport and then drive to your home. Let a gate agent know if you are flexible. In my case, a London to New York City ticket became a London to Dusseldorf to Frankfurt to Washington, D.C., to New York City journey. This route was knottier and tiring, but it spared me from being stranded at an airport overseas during Christmas. Flights to Washington, D.C., happened to be in less demand than flights to New York City, and once I was in the U.S. I could find a way to get to my family's house. Using weather.com, I quickly found out that conditions were better at D.C., than Newark—which was being buffeted with high winds. Some airlines will even convert your plane ticket into a train ticket: Lufthansa, for instance, converted my plane ticket between Dusseldorf to Frankfurt into a train ticket, and I made it in time. I was offered the same choice between D.C. and N.Y.C. Luggage can ruin your day. I faced a dilemma about what to do with my bags. It was the morning, and I was at Frankfurt Airport. Nearly every flight to the U.S. scheduled to fly before noon had been canceled. A gate agent offered to book me on a 1 o'clock flight. What were the chances that the 1 o'clock flight would also be canceled? If I checked my bags, and then the flight was canceled, I would have to stand in line to reclaim my bags before I could be rebooked onto another flight, which would make it even less likely I would make it home in time for Christmas. But the odds were awful on the other side of the bet, too. I kept my bags, and then waited until two hours before the flight, when it seemed likely that the plane would truly take off. But I had waited too long. The line for checking bags was at least three hours' long, with about 400 people in it. There was no way I would board the plane in time. Luckily, I did some sleuthing and found a shorter, less-well-known line for checking bags—back outside of the Frankfurt Airport, "curbside," at the adjacent train station—and managed to make it back through security and to the gate in the nick of time.

It's popular for middle-class Europeans to "take off" the year before going to college, and many spend the year traveling. The idea is to allow older teens some time to discover themselves and learn about other cultures. Two recent studies link participation in a gap year to increased graduation rates. if (WIDGETBOX) WIDGETBOX.renderWidget('f14524be-a978-476e-927e-f8dd57408f66');Get the Poll Creator Pro widget and many other great free widgets at Widgetbox! Not seeing a widget? (More info)Americans haven't much liked the idea of a "gap year," either before or after college. Fewer than 10,000 are estimated to do it each year. Those who do take a gap year tend to visit Australia most. "Down Under" saw a 25 percent jump in visa grants for its " " target="_blank">working holiday youth visas" in 2009-2010. But gap and bridge years may become more popular. Since 2009, Princeton University has been running a "Bridge Year" program that financially supports up to 10 percent of their incoming class in doing nine months of volunteer work in other countries before they start their freshman year. Harvard and Yale are copying with similar programs.Have any advice for any students thinking about taking a gap year? And what would you do with a gap year? (Post a comment, below.) Having the support of an organized program could make a gap year useful for an 18-year-old.

As of late last week, visitors to London can now rent bicycles in the city center for as little as one pound for a 30-minute ride. Since July, about 5,000 so-called "Boris bikes" (named after the mayor) have been kept in automated racks posted throughout the city. Until now, only local residents were allowed use the two-wheelers. But as of Thursday, you can use your American credit card to unlock a bike, paying a small access fee and an hourly fee. The first half-hour is free. I tested out the service today, walking up to a kiosk that stood next to a flock of the blue bikes, all painted in the prominent Barclay's bank logos.I used the kiosk's touch screen to request a 24-hour pass. I inserted my American credit card, and £1 was deducted, plus a currency exchange fee for my issuing bank. I then was asked to re-insert my card to finalize the transaction, and this took about 40 seconds. I was given a slip of paper with a code on it. I walked over to the first bike that looked good to me—the one already adjusted to a decent seat height—and punched in the code, unlocking a three-speed. I biked around for less than a half hour before I re-docked the bike at a different station. After shopping for Christmas cards, I went to a kiosk, and re-entered my credit card. It recognized that I still had many hours left on this pass, and I received a new code, and unlocked a new bike. Because I only biked for less than 20 minutes, I wasn't hit with another charge. Unlike in many U.S. cities, there are no helmet laws in London. I felt relatively safe riding around, as the traffic congestion charge has reduced the amount of traffic in downtown London. Finding a bike station is easy. There are 352 docking stations scattered in the city's heart. Print out a free map for routes and bike paths online or pick up a copy from a tourist official. (One catch: You have to be at least 14 years old to ride one of these bikes, and at least 18 to rent one for casual use.) tfl.gov.uk/barclayscyclehire MORE FROM BUDGET TRAVEL Video: How to bike in Paris Bicycling New Orleans One guy, one bicycle, one cross-country tour Traveling India by app
