Flying into the Andes is weird. You’re coasting over these jagged, brown and green peaks that look close enough to touch, and then suddenly, the ground rises up to meet the plane. When you fly to Cusco Peru, you aren’t just taking a domestic hopper; you’re entering one of the most technically challenging commercial flight paths in the world.
The Alejandro Velasco Astete International Airport (CUZ) sits at roughly 10,800 feet. That is high. Really high.
Most people worry about the turbulence. Honestly? The turbulence isn't the issue. It's the air. The air is thin, which means planes have to fly faster to maintain lift. It also means that if you’ve spent the last few days at sea level in Lima, your body is going to feel like it just got hit by a metaphorical sack of bricks the second you step off that pressurized cabin.
The Logistics of Getting There
You can’t fly direct from the States or Europe. Not yet, anyway. There’s been talk for a decade about the Chinchero Airport project, but for now, you’re almost certainly going through Lima’s Jorge Chávez International Airport (LIM).
Lima is the bottleneck.
Most travelers arrive in Lima late at night, stay in a hotel in Callao or Miraflores, and then head back for an early morning flight to the mountains. Why early morning? Because the winds in the Andes are unpredictable. By 2:00 PM, the crosswinds in the Cusco valley often get so squirrelly that airlines start canceling or delaying flights. If you book a 4:00 PM flight to Cusco, you’re basically gambling with your vacation schedule. Don't do that. Take the 7:00 AM or 8:00 AM flight. You’ll thank me when you’re sipping coca tea by noon instead of sitting on a terminal floor in Lima.
LATAM is the big player here. They have the most frequencies. Sky Airline and JetSmart are the low-cost options. They're fine, but be careful with the baggage rules. They will nail you for a backpack that’s a half-inch too wide.
The Reality of Altitude Sickness (Soroche)
Let's talk about the biological tax of your flight.

The moment you land, you might feel fine. Euphoric, even. The air is crisp, the sky is a shade of blue you don't see in smoggy cities, and the mountains are breathtaking. Then, about four hours later, the headache starts. It’s a dull throb behind the eyes.
This is soroche.
The mistake most people make when they fly to Cusco Peru is trying to do too much on Day 1. They land, drop their bags, and immediately go for a "light hike" to Sacsayhuamán. That is a terrible idea. Your heart is already working 20% to 30% harder just to keep your blood oxygenated while you're sitting still.
- Hydrate like it's your job. * Eat light. Digestion slows down at altitude. A heavy steak dinner on your first night is a recipe for a miserable, sleepless night.
- Coca tea works. It’s not a myth. It’s a mild stimulant that helps with the headache, though don't drink five cups before bed unless you want to be staring at the ceiling until dawn.
Some doctors suggest Acetazolamide (Diamox). I’m not a doctor, but I’ve seen it work for plenty of people. Just keep in mind it’s a diuretic. You will be peeing constantly. Also, it makes carbonated drinks taste like pennies. If you're a Coke or beer fan, be warned.
Why the Approach is Legally "Special"
Pilots need special certification to land in Cusco. It’s not a "point and click" landing. Because of the surrounding topography, planes have to maneuver through a specific valley opening.
If there is heavy cloud cover, they won't even try.
This is why "flight seen" is a common phrase in Peruvian travel circles. If the pilot can't see the runway clearly, they will circle for twenty minutes and then head right back to Lima. It’s frustrating, but when you see the mountains surrounding the city, you realize why they don't take chances.

Moving Toward the Sacred Valley Immediately
Here is the pro tip that seasoned Peru travelers swear by: don’t stay in Cusco the first night.
When you fly to Cusco Peru, you’re landing at 10,800 feet. However, the Sacred Valley (towns like Pisac, Urubamba, or Ollantaytambo) sits significantly lower, around 9,000 feet. That 1,500-foot difference is the margin between feeling "a bit winded" and "I think my head is going to explode."
Grab a taxi or a pre-booked transfer straight from the airport to Urubamba. Spend two days there. Let your red blood cells multiply. Then, move back up to Cusco once you’re acclimated. It makes the entire trip 100% more enjoyable.
Booking Your Seat: Left or Right?
This is a small detail that makes a massive difference for your Instagram feed.
When flying from Lima to Cusco, sit on the left side of the plane (Seat A). As you approach the Andes, the left side offers the most dramatic views of the snow-capped peaks. If you sit on the right, you’re mostly looking at the brown, arid slopes of the coastal range until the very end. On the way back (Cusco to Lima), sit on the right side.
The Cost Factor and Seasonality
Peru doesn't really have four seasons. It has "dry" and "wet."
Dry season is May through October. This is when the sun is out, the sky is clear, and flight prices to Cusco skyrocket. You’ll also deal with the most crowds.

Wet season (November through April) is cheaper. But remember what I said about the clouds? Flights are much more likely to be delayed or cancelled in January or February due to rain and visibility issues. If you’re traveling during the rainy season, give yourself a one-day buffer. Don't book your Machu Picchu train ticket for three hours after your flight is scheduled to land. You’re asking for heartbreak.
The Chinchero Controversy
I’d be remiss if I didn't mention that the way we fly to Cusco Peru is changing. There is a massive new airport being built in Chinchero. It’s controversial.
Environmentalists and archaeologists are worried it will ruin the "vibe" of the Sacred Valley and put too much stress on the local water table. On the other hand, the current airport is smack in the middle of the city. Literally. Houses are built right up to the fence. It can't handle large, long-haul jets.
When Chinchero opens (whenever that actually happens, as deadlines keep sliding), we might see direct flights from Miami or Madrid. For now, enjoy the chaotic charm of the old airport. There’s something special about walking across the tarmac in the thin mountain air, seeing the "Cusco" sign, and realizing you've finally made it to the heart of the Incan Empire.
Practical Steps for Your Arrival
- Book an AM Flight: Aim for a departure before 9:00 AM to avoid the afternoon wind cancellations.
- Pre-arrange Transport: The taxi drivers at the Cusco airport are aggressive. They will surround you the moment you exit. Having a guy holding a sign with your name on it is worth the extra $10 for the peace of mind.
- Carry Cash (Soles): While many places take cards, the smaller shops and taxis in Cusco are strictly cash. There are ATMs in the airport, but they often have low withdrawal limits.
- Pack Layers: You will be hot in the sun and freezing the second you step into the shade. The temperature swing is wild.
- Check Your Lungs: If you have asthma or heart conditions, talk to a doctor before booking. The altitude is no joke and can exacerbate underlying issues quickly.
Forget the "perfect" itinerary you see on social media. Your first day in Cusco should involve nothing more than a slow walk to a cafe and a lot of water. Respect the mountains, and they'll show you a good time. Ignore the altitude, and you'll spend your trip looking at the inside of a hotel bathroom. Your choice.
Go check your flight times now. If you're on that afternoon rotation, see if you can swap it for an early bird special. It’s the smartest move you’ll make all week.
