Here is a quick overview describing some of the new trends in the travel industry. If you haven’t traveled in 2007, check out these helpful hints.

• Passports
  Just a reminder, as of January 23, air travelers visiting the Caribbean, Bermuda, Canada or Mexico (and all other international destinations) will need passports to return to the United States.
  

• New technology
  In-flight additions
  For better or for worse, cell phones and wireless internet connections are making their way onboard planes. This month, Emirates Airlines will launch the first in-flight cell phone capability. Callers will be charged international roaming rates, generally about $1 to $2 per minute. U.S. carriers probably won't offer the service this year, if at all, but it is on the horizon.
  
  Wi-Fi is more of a possibility, however. A recent CNN report says 59 percent of airlines plan to have wireless internet capability by spring of 2008.
  
  
• New websites
  ExpertFlyer.com offers detailed information on flight availability and status, as well as seat maps. While much of this information is available on most airlines' own websites, ExpertFlyer.com is unique in that it displays the different “fare buckets” available on any given flight, which can help travelers identify the tickets that are least expensive, most flexible, or easiest to upgrade. It also displays how many seats are left on each flight, which can help travelers determine if snagging a standby seat is possible — before arriving at the airport. By summer 2007, expertflyer.com will offer a free version before you subscribe.
