Here’s something that doesn’t tend to appear in the travel brochure: the hardest part of your first big trek might happen before you ever lace up your boots. It happens at 11:47 p.m. on a travel website, when you’re staring at 47 flight options and wondering why one is $400 cheaper than the rest.
(Spoiler: there’s usually a not-great reason.)
Not to worry. Here’s how to build a flight plan that gets you and your bag to the trailhead on time.
Get there early. Then a little earlier.
If you remember nothing else, remember this: plan to arrive at least one day before your trip starts. For long hauls like Nepal and Tanzania, two is even better if you can swing it.
Flights get delayed. Connections get missed. Bags take the scenic route. An extra day turns a travel disaster into a minor inconvenience. It also gives you a head start on jet lag before you start climbing. Nobody wants to begin a 12-day trek feeling like they got hit by a truck.
Book it all on one ticket
This is critical. When your whole journey is on a single reservation, with one confirmation number from start to finish, the airline is responsible for getting you to your final destination. If your first flight runs late and you miss your connection, they rebook you. Your bag is checked all the way through.
On the other hand, when you piece together separate tickets to save a few bucks, you’re on your own. If flight one is late and you miss flight two, the second airline doesn’t care. You may be buying a brand-new ticket at the counter and hauling your bag out to recheck it yourself.
That $400 savings disappears fast.
How long of a layover is long enough?
Our rule of thumb:
- Domestic connection: 90 minutes, minimum.
- International connection: 2 to 3 hours.
- Any connection where you clear immigration, customs, or security again: 3 hours or more.
That last one matters most on the way home. At your first U.S. airport, you’ll go through passport control, grab your bag, clear customs, recheck your bag, and go back through security. That’s a lot of lines. Don’t try it in 75 minutes.
Don’t overdo it in the other direction, though. A 14-hour layover sounds fine until hour nine, when you’re sitting on an airport floor. If a long one can’t be avoided, look into an airport hotel or a lounge day pass.
Which route is best?
Fewer connections beats a cheaper fare almost every time. Every stop is just another chance for something to go sideways.
A few pointers for where we trek:
- Nepal: Most travelers connect through a big hub like Doha, Dubai, or Istanbul. Those carriers are reliable and comfortable for the long legs.
- Tanzania: Fly into Kilimanjaro International (JRO), not Dar es Salaam. Common connections include Amsterdam, Doha, Istanbul, and Addis Ababa.
- Peru: You’ll land in Lima, then hop a short flight to Cusco. You clear immigration and customs in Lima, which usually means collecting and rechecking your bag, so give that connection extra time.
- Bhutan: Only a couple of airlines fly into Paro, from a handful of cities. Choose your gateway city first, then plan backward from there.
For other locations, let us know and we can help sort them out.
A few last tips
- Don’t book the last flight of the day on any leg. Miss it, and you’re sleeping at the gate.
- Get travel insurance that covers delays and lost bags.
- Screenshot your itinerary. Wi-Fi isn’t a given.
- Double-check airport codes before you hit “purchase.”
Get the flights right, and everything after gets a whole lot easier. The mountains will wait for you. Your connecting flight won’t.
