If you're looking for a LATAM Airlines seat upgrade, you've come to the right place. Whether you want to stretch out in Premium Economy or lie flat in Premium Business, LATAM offers several ways to move up the cabin ladder—and for 2026, the program has some new wrinkles you'll want to know about. The key is understanding your options: miles, cash bids, elite status perks, and even last-minute airport offers. Let's break down exactly how to snag that better seat without overpaying .
Quick Overview
Before we dive deep, here's the fast-track version of everything you need to know about upgrading your LATAM flight:
Key Benefits of Upgrading with LATAM:
Premium Economy: Blocked middle seat (you get window or aisle with empty seat beside you), 40% more recline, 10+ cm extra legroom, Priority Boarding Group 1, Priority Baggage, 1 checked bag at 23 kg, premium meal service with complimentary beverages, and VIP Lounge access on international routes
Premium Business: 180° lie-flat seats, restaurant-quality dining, amenity kits, 2-3 checked bags, full lounge access, and complete priority service from check-in to baggage claim
Important Rules for 2026:
Free upgrades: Available only to elite members using upgrade coupons earned through status (Gold, Gold Plus, Platinum, Black, Black Signature)
Paid upgrades: Anyone can bid for upgrades, pay with LATAM Pass miles, or purchase at check-in (subject to availability)
Eligibility: Most fare classes qualify except Basic Economy; higher fare types get upgrade priority
LATAM Pass 2026 changes: The 50% bonus qualifying points on Full fare and Premium cabins is no longer automatic—you must select it as a benefit in the LATAM Pass app
Fees & Charges Snapshot:
Bid for Upgrade: The cost for this method typically ranges from $50 to over $400, depending heavily on the flight route, season, and current demand.
Miles Upgrade: If using LATAM Pass miles, you can expect to redeem between 5,000 and 50,000+ miles to secure a seat in a higher cabin class.
Airport Last-Minute Upgrade: Purchasing an upgrade at the check-in counter or gate usually falls in the $100 to $500 range, with prices often dropping closer to departure if seats remain available.
Elite Coupons: For LATAM Pass elite members (Gold and above), upgrade coupons are offered free of charge as a status benefit, subject to availability in the designated booking class.
Special Cases:
Seat/baggage refunds after upgrade: If you purchased seats or bags before April 15, 2025, and then receive an upgrade, you can request a refund. After that date, refund eligibility depends on the fare class of your upgraded ticket .
Infants & minors: Upgrade eligibility follows adult ticket; lap infants may not receive full premium benefits.
Baggage allowance: Your allowance matches the new cabin class post-upgrade.

Understanding LATAM Airlines Seat Upgrade Policy
LATAM's upgrade ecosystem isn't a one-size-fits-all system. The airline offers multiple paths to a better seat, and the best choice depends on your budget, flexibility, and how you originally booked your ticket.
What Fare Types Qualify for Upgrades?
Not all tickets are created equal when it comes to upgrade eligibility. Here's what works and what doesn't:
Basic Economy: Generally ineligible for upgrades—you'll need to stick with your original seat
Light, Plus, and Top Fares: Eligible for paid upgrades and miles redemptions
Full Fare Economy: Highest upgrade priority for elite members and paid upgrades
Premium Economy: Can upgrade to Premium Business using miles or bids
Pro tip: If you're planning to pursue an upgrade, avoid Basic fares entirely. The small savings upfront will lock you out of all upgrade opportunities later.Read More: LATAM Airlines Baggage Policy
LATAM Upgrade Options: The Complete Menu for 2026
You have five primary ways to move up a cabin on LATAM flights:
Bid for Upgrade (PlusGrade): Name your price for an upgrade and find out 24-48 hours before departure if you've won
Miles Upgrade: Redeem LATAM Pass miles for confirmed cabin upgrades
Airport Upgrade: Purchase available premium seats at check-in counters or gates
Elite Status Coupons: Gold and higher members receive complimentary upgrade certificates
Online Upgrade: Manage your booking on LATAM.com to see instant purchase offers
How to Upgrade LATAM Flight: Step-by-Step Methods
Method 1: LATAM Bid for Upgrade
The bidding system (powered by PlusGrade) lets you propose what you're willing to pay for Premium Economy or Premium Business. Here's the process:
Receive an email invitation 7-10 days before departure (check spam folders!)
Use the slider to select your bid amount—you'll see a meter showing "weak," "fair," or "strong" bid strength
Enter payment details (you're only charged if you win)
Wait for confirmation 24-48 hours before your flight
If successful, your new seat is assigned and boarding pass updated automatically
Real-world scenario: Maria booked a Santiago to Lima flight in Economy Plus for $189. She received a bid invitation for Premium Business, offered $95 (a "fair" bid), and won. She ended up paying $284 total for a seat that retails for $650+. That's a win.
Method 2: LATAM Upgrade with Miles
Starting in late 2025, LATAM Pass members gained the ability to redeem miles specifically for cabin upgrades . To use this option:
Log into your LATAM Pass account
Navigate to "My Trips" or search for your booking
Look for "Upgrade with Miles" option
Select your desired cabin class
Confirm the miles deduction and receive immediate upgrade confirmation
Important: Miles upgrades are capacity-controlled. They disappear quickly on popular routes like São Paulo-Miami or Santiago-Madrid. Book these as early as possible.
Method 3: LATAM Upgrade at Check-in
If you're feeling spontaneous, wait until check-in opens (72 hours before departure). LATAM often releases unsold premium seats at discounted rates. Here's what to do:
Online check-in: The upgrade offer appears before seat selection
Airport kiosk: Look for "Upgrade Cabin" option
Check-in counter: Simply ask the agent, "Are there any paid upgrades available today?"
Caveat: Last-minute upgrades are first-come, first-served. Popular routes sell out fast.
Method 4: Elite Status Upgrade Coupons
LATAM Pass elite members (Gold and above) earn upgrade coupons based on their tier :
Gold: Requires 15,000 qualifying points or 20 segments flown. Members receive courtesy upgrades using complimentary coupons when available.
Gold Plus: Requires 30,000 qualifying points or 35 segments flown. In addition to upgrade coupons, members enjoy same-day domestic flight change flexibility at no extra cost.
Platinum: Requires 40,000 qualifying points or 45 segments flown. Benefits include complimentary LATAM+ seat selection at booking and enhanced upgrade eligibility.
Black: Requires 75,000 qualifying points or 75 segments flown. Members receive priority clearance for airport upgrades over lower-tier elites.
Black Signature: Requires 160,000 qualifying points or 120 segments flown. This top tier guarantees the highest upgrade priority in the system, often clearing before other status levels.
Method 5: LATAM Premium Economy Upgrade Direct Purchase
Sometimes the simplest path is booking Premium Economy from the start. On regional South American routes, the price difference is often modest—$40-120 more than standard Economy—but includes baggage, meals, and priority perks that would cost more à la carte.
LATAM Seat Upgrade Cost and Fees in 2026
Upgrade pricing follows a dynamic model. Your actual cost depends on:
Route distance: Longer flights cost more
Cabin difference: Economy → Business costs more than Economy → Premium Economy
Demand: Holiday periods and peak travel days see higher minimum bids
Original fare class: Higher original fares get lower upgrade costs
Estimated LATAM business class upgrade price ranges:
Santiago to Lima (3-4 hour flight):
Upgrade to Premium Economy: Expect to pay between $45 and $120.
Upgrade to Premium Business: Expect to pay between $150 and $350.
São Paulo to Miami (8-9 hour flight):
Upgrade to Premium Economy: Not available on this widebody route.
Upgrade to Premium Business: Expect to pay between $400 and $900.
Bogotá to São Paulo (6 hour flight):
Upgrade to Premium Economy: Expect to pay between $60 and $150.
Upgrade to Premium Business: Expect to pay between $250 and $500.
Lima to Madrid (12 hour flight):
Upgrade to Premium Economy: Not available on this long-haul widebody route.
Upgrade to Premium Business: Expect to pay between $600 and $1,200+.
Note: Premium Economy is only available on narrowbody aircraft (A319/A320/A321) for regional routes; widebody international flights offer Premium Business directly .
LATAM Upgrade Eligibility: Who Can Upgrade?
Understanding eligibility prevents disappointment at the airport. Here's the breakdown:
Eligible for upgrades:
Tickets booked in Light, Plus, Top, or Full fares
LATAM Pass members with sufficient miles
Passengers who receive bid invitations
Elite members using upgrade coupons
Ineligible for upgrades:
Basic Economy fares (no exceptions)
Group bookings (special rules apply)
Tickets purchased with certain corporate discounts
Already-checked-in passengers (except at airport)
Special note for 2026: The automatic 50% qualifying points bonus on Premium cabins now requires you to actively select this benefit in the LATAM Pass app. Missing this step means losing out on valuable points toward status .
What Happens to Your Original Purchase When You Upgrade?
This is where many travelers get confused. If you upgrade, here's what happens to your existing seat selection and baggage purchases:
Seats purchased before upgrade: Refund eligibility depends on purchase date. Before April 15, 2025? You can request a refund. After that date? It depends on the fare conditions of your upgraded ticket .
Baggage purchased before upgrade: Same rules apply—check your original fare conditions
LATAM Pass miles earned: You'll earn miles based on your original ticketed fare class, not the upgraded cabin (unless you paid cash for the upgrade)

Expert Tips to Maximize Your Upgrade Chances
1. Bid strategically, not emotionally. The "strong" bid indicator isn't always necessary. On less popular routes or midweek flights, a "fair" bid often wins.
2. Check upgrade availability before transferring miles. Once miles are in LATAM Pass, they can't be transferred back out. Confirm availability first.
3. Join LATAM Pass even if you rarely fly. Basic membership is free and unlocks miles upgrade eligibility .
4. Monitor your email 10 days before departure. Bid invitations arrive automatically for eligible bookings—but they can land in spam.
5. Consider Premium Economy outright on regional flights. The bundled value often beats piecemeal upgrades, especially if you need checked baggage .
6. Ask at the gate. Even if online upgrades show "unavailable," gate agents sometimes release unsold premium seats 30-45 minutes before boarding.
7. Know the 2026 status changes. If you're chasing elite status, that 50% qualifying points bonus now requires active selection in the app. Don't leave points on the table .
Common Upgrade Mistakes to Avoid
Buying Basic Economy hoping to upgrade later. You can't. Ever.
Waiting until the last minute on popular routes. Upgrade inventory for Lima-Cusco or Santiago-Easter Island disappears weeks ahead.
Assuming miles upgrades are always available. Capacity controls mean limited seats.
Forgetting to check bid status. Winning bids require no action, but losing bids free you to try airport upgrades instead.
Not factoring in baggage savings. Premium Economy includes a checked bag; the upgrade sometimes pays for itself.
