How Post-it Notes Can Extend the Life of Your Passport

For frequent international travelers, there are few encounters more quietly frustrating than when a customs officer stamps a completely blank page with a flagrant disregard for visa space.

Visas require at least a full blank page — and some countries may require between two and four blank pages.

But there’s one clever trick using common office supplies that can keep passport pages pristine for future visas.

Chris Chamberlin of Australian Business Traveler recommended saving blank space in your passport with two Post-it Notes and a gently written note.

Stick a note on each page you would like to remain blank with a polite and concise message to the effect of “stamp elsewhere.” In his passport, Chamberlin has written “Please kindly stamp on any other page. Saving space for one visa.”

“I’ve been travelling with these in my passport for over a year now to preserve my last remaining ‘double blank’ page, and all the passport officers I’ve encountered have been most obliging,” Chamberlin wrote.

Chamberlin estimates that the trick will have extended his passport’s life by about two years.

Because the Post-it Notes are impermanent and easily removed, they do not break any passport regulations. And, if worst comes to worst, the immigrations officer can rip off the Post-it and stamp wherever they please.

Why We Love the Caribbean

As Caribbean islands begin to recover from two devastating hurricanes, travelers from around the world have displayed an outpouring of support for some of their favorite travel destinations.

Known for their hospitality, gorgeous beaches, and natural beauty, the islands have long attracted visitors from around the world. The Caribbean is also one of the most versatile regions, perfect for honeymoons, baby moons, and solo travelers.

Puerto Rico, Dominica, the U.S. Virgin Islands, and St. Martin suffered some of the worst damage, while the Bahamas and Jamaica escaped relatively unscathed. This hurricane season has already been especially destructive, and the process for rebuilding on each island can take anywhere from a few weeks to up to a year.

The region will recover in time, and as the process continues, the editors from Travel + Leisure took a moment to reminisce about some of their favorite memories from the Caribbean.

These Are the 8 Worst Airports for Flight Delays

Airports across the country are bracing for a perfect storm that threatens to leave travelers stuck in security lines of epic lengths. The cause? Cheaper airfare is expected to drive a record number of flyers to airports around the country, but the Transportation Security Administration has too few security screeners to deal with the influx.

Lawmakers in Washington have given the TSA clearance to hire more screeners (and pay existing ones for overtime work), but it’s unclear if the agency can ramp up in time to deal with the summer rush. Travelers in cities like Atlanta and Chicago are already reporting hours-long security lines. Some are rallying around the Twitter hashtag #IHateTheWait to vent their frustrations. Several airports have recommended travelers arrive at least three hours early for their flights, though even that may prove insufficient.

At which airports do travelers have it the worst? Of the country’s busiest airports, these are the eight with the lowest percentage of on-time departures between January and March of this year, according to data from the Department of Transportation. That metric isn’t a perfect stand-in for security delays, but if you’re flying out of one of them, it’s best to arrive with plenty of time to spare.
