3 Most Intriguing New Facebook-Based Travel Tools

Perhaps the only thing more associated with Thanksgiving than turkeys and pilgrims is airport-induced rage. Hours of delays, lost luggage, and never-ending security lines can surely leave a bad taste in your mouth. A major part of your holiday happiness, therefore, can be tied to the airports through which you travel. If you're lucky enough to get a good one, flying can be a breeze: the sunny halls, central-hub design, and easy-to-navigate tram system at Tampa International Airport means I never have to worry about being a Thanksgiving Grinch on my way home for the holidays. But millions of other travelers aren't so lucky. CNN.com compiled a list this week of the most hated airports around the world, with reasons why each earned this dubious distinction: 10. São Paulo-Guarulhos International, São Paulo, Brazil: "just 41 percent of all flights leave on time" 9. Perth Airport, Perth, Australia: "a reviled pair of domestic terminals (home of two-hour taxi-line queues, atrocious check-in lines, overpopulated gates and meager lounges)" 8. Tribhuvan International, Kathmandu, Nepal: "primitive yet officious check-in procedure, starring a roulette wheel of underpaid security agents" 7. John F. Kennedy International, New York, United States: "a dim, surly, unbearably congested airport reeking with attitude and unapologetically long immigration lines" 6. Jomo Kenyatta International, Nairobi, Kenya: "cramped spaces; long lines; inadequate seating; frequent power outages; tiny washrooms hiding up several flights of stairs; shabby duty free shops; overpriced food outlets; and business class lounges worthy of a shelter in mid-city Los Angeles" 5. Ninoy Aquino International, Manila, Philippines: "ground crew strikes, unkempt conditions, soup kitchen-style lines that feed into more lines and an overall sense of futility" 4. ToncontÍ n International, Tegucigalpa, Honduras: "second most dangerous airport in the world" 3. London Heathrow, London, England: "long walks (or, more commonly, runs) between gates to a frenzied soundtrack of ‘last call' announcements" 2. Los Angeles International Airport, Los Angeles, United States: "a dramatically undersized and moribund one with the architectural élan of a 1960s correctional facility" 1. Paris-Charles de Gaulle, Paris, France: "the baffling circular layout is worsened by warrens of tunnel-like structures, dismissive staff and seething travelers waiting forever in the wrong queue...the worst part may be this airport's aura of indifference to it all" More often than not, we don't hate an airport for something major, such as Tegucigalpa's spotty safety record. It can be the little things that bug us: long taxi lines, lengthy walking times between terminals, uncomfortable seats, too few outlets.

We've heard about the trouble with snow globes. And wrapped gifts. And even big hairdos. And when I checked in at Washington DC's Reagan National Airport last weekend, I probably should have known I was setting myself up for scrutiny. After all, our story "7 Surprising Items That Set Off Airport Security" pointed out that even the tiniest bit of gum-wrapper foil wadded up in a pocket can set off airport metal detectors. And yet, it never occurred to me that my snazzy gold sweater—shot through with lurex threads—would earn me a TSA patdown. "Cute top, but not airport friendly," the TSA agent said as she searched me for weapons. Apparently, the metallicized thread in the sweater yarn was making the scanner go crazy. That got me thinking about all the other ways a festive holiday sweater could cause a travel delay: jingle bells dangling from Rudolph's harness, tiny metal ornaments, and the worst offender of all—battery-powered mini-lights strung on an intarsia Christmas tree. Okay, so probably no savvy Budget Travel reader would be silly enough to try to fly in a battery-powered sweater, but gold threads? An easy mistake to make—and lucky for you, reader, one that I've made for you. Have you ever been singled out for a similarly silly-seeming reason? What are the most surprising things you've been pulled aside for by the TSA?

London's Heathrow Airport is the world's busiest international airport, but it's too full and it can't grow any further. Protests by local residents have prevented an additional runway and terminal from being built. Rival airport Gatwick faces a similar problem. So, government officials have turned their eye south to the idea of building a brand new airport where no local residents can possibly protest it—in the middle of the Thames Estuary. Earlier this month, the plan for a new airport was unveiled to the public by famous British architect Norman Foster. The Thames Hub would be set on an island near the mouth of the Thames River. It would be connected to the city by a $10 billion "orbital shuttle train," says the Times of London. The airport could be partly financed by private investment or international sovereign wealth funds, claim officials. This weekend, the Financial Times reported that the idea of building an alternative hub airport south of London has won support from key players: Chancellor George Osbourne (who oversees the British Treasury), the new Transport Secretary Justine Greening, and the prime minister's main policy advisor Steve Hilton. The mayor of London Boris Johnson has been advocating for a new airport since he released a report in January saying the city's economic future depends on such expansion. Air passenger numbers are expected to double in the next 20 years, and British officials worry that airlines may re-route their flights to rival, larger airports, such as Schiphol in Amsterdam, Charles de Gaulle in Paris, Frankfurt am Main, and Dubai International. Unlike these airports, Heathrow has not been expanded since it was first built in 1946. Its two runways already operate at 98 percent of capacity on the typical day. Britain isn't the first to consider moving its main transit hub to a larger airport. Moving a hub airport is something other cities, such as Milan, Hong Kong, Paris, and Tokyo, have done successfully. Governments have talked of expanding London's airport capacity since the 1960s, though. The debate is likely to continue for another couple of years before a final decision. So travelers shouldn't expect relief any year soon. What do you think about Heathrow? Does it deserve replacing?

Window, aisle or middle? Countless fliers have faced that age-old question, the answer to which could have serious implications for the enjoyment of any flight. A collection of online tools and apps is now helping passengers settle the issue once and for all. if (WIDGETBOX) WIDGETBOX.renderWidget('47422524-2ba5-4fb1-9cb7-3d939d8a6a96');Get the Poll Creator Pro widget and many other great free widgets at Widgetbox! Not seeing a widget? (More info) The question of seating is actually quite complicated. Aside from the three classic options, there are exit–row seats, bulkhead seats, seats located in the proximity of restrooms, plus physical differences in the seats themselves. If you’re a seasoned flier, you may well have all these variables committed to memory already. Unfortunately, what you can’t control is your fellow passengers, and by the time you scour an airline’s online seating chart for your beloved aft/aisle/exit row throne, some rube may have snagged that very seat without even knowing that he’s in possession of the gold standard. What’s a discerning flier to do? With ExpertFlyer's new Seat Alerts, you might still have a chance at reclaiming your rightful place. ExpertFlyer allows you to search the seating map for an upcoming flight and set up a Seat Alert for any seat (or range of seats) you wish. If that seat opens up before the flight, ExpertFlyer will send you an email notification of the vacancy so that you can contact the airline and change your seating arrangement. (Beware of additional airline fees for doing so.) With a free ExpertFlyer account, travelers can set up one Seat Alert at a time. Additional Alerts cost $.99 each, or users can purchase monthly Basic ($4.99) or Premium ($9.99) accounts that allow up to thirty alerts plus lots of other features. But what if you don’t know a bulkhead from a bassinet seat? There are tools for that, too. Paid ExpertFlyer accounts come complete with reviews and ratings from SeatGuru, permitting even beginners to the cutthroat world of airline seating to figure out which seats are best for a given flight. SeatGuru not only provides free color-coded seating maps, but also detailed comments on leg room and degrees of recline. SeatGuru is the venerable king of the airline–seating industry—it launched back in 2001—but there are newcomers challenging the crown. Seat Authority, a $2.99 iPhone app, gives fliers similar information in a handy portable package. Aside from over a hundred seat maps, Seat Authority provides photos of the seats in question and all the necessary comfort metrics: width, seat pitch, and recline. For ease of use, the recently launched Jets iPhone app is hard to beat. Jets displays crisp seating maps from its database of flights, and lets users select specific seats to get the pros and cons of each. Even the most inexperienced flier can develop an understanding of seating dynamics from Jets’ clean graphical interface, and at $2.99, the app costs the same as Seat Authority. Both are a cheap price to pay for the assurance that you won’t end up wedged against a bulkhead or suffering from the foot traffic—and aromatics—of a nearby restroom.
