Enulow cost airlines international flights can look like a steal, until you add a carry-on, a checked bag, and seats together, and the “cheap” ticket stops being cheap. This guide keeps you focused on what matters: your total trip cost, not just the headline fare.
You’ll learn how to spot genuinely cheap long-haul fares from Brazil to Europe, how to avoid common fee traps during checkout, and how to pick the right airline for your trip style (backpack-only, one checked bag, family travel, or last-minute).
Prices, routes, aircraft, and baggage rules change often, sometimes by season and sometimes by fare type. Always confirm the final total, baggage allowance, and change rules on the airline’s own website before you buy. This article is for general travel planning only, not financial or legal advice.
Low cost airlines international flights, what they really mean (and why the cheapest fare is not always the cheapest trip)
When you see “low cost” on international routes, it can mean two different things:
1) A true low-cost carrier model (LCC/ULCC)
These airlines sell a very low base fare and charge separately for most extras. On long-haul Brazil to Europe routes, pure long-haul ULCC options are limited, so you’ll often encounter this model mainly on short intra-Europe connections after you land.
2) A full-service airline selling a low-fare class
Many network airlines now sell “basic” or “light” fares that look like low cost airlines international flights, but operate on a traditional carrier. The trade-off is similar: fewer inclusions, more add-ons.
In plain language, the cheapest ticket often includes:
- A small personal item (under-seat bag)
- A seat assignment that might be random (or paid if you want to choose)
- Limited flexibility (changes can be expensive, sometimes not allowed)
What often costs extra on international flights:
- Full-size cabin bag (carry-on) or “trolley bag”
- Checked baggage
- Seat selection (especially to sit together)
- Meals, alcohol, and sometimes even standard snacks
- Changes, name corrections, or missed-connection support (when you self-transfer)
The result is simple: low cost airlines international flights are only “low cost” when the fare matches how you travel.
A quick pre-booking checklist (use this every time)
Before you click Pay, do a fast total-cost check:
- Bags: Do you need a carry-on, a checked bag, or both?
- Seats: Do you need to sit together, or can you accept random seats?
- Connections: Is it one ticket, or separate tickets with a self-transfer?
- Changes: If your plans move by a day, what happens?
- Airport costs: Does the itinerary force an extra overnight or a long transfer?
If baggage is your biggest unknown, skim a practical refresher like NerdWallet’s guide on tips to save on baggage fees and then compare that advice with the airline’s current rules at checkout.
Common extra fees on international flights, baggage, seats, changes, and airport add ons
Here’s how fees usually show up during booking, and how to reduce them:
- Carry-on upgrade: You pick a “hand baggage” add-on, often tied to priority boarding.
Tip: pay online early, the airport price is often higher, and size checks can be strict. - Checked bag fee: The first checked bag is commonly excluded from the lowest fare.
Tip: add bags during the first booking flow, not later, and watch weight limits. - Seat selection: You pay to choose seats, and “front,” “extra legroom,” or “preferred” seats cost more.
Tip: if you must sit together, price it in now, don’t assume the gate can fix it. - Change and cancellation fees: Basic fares can be restrictive.
Tip: if dates might move, compare the next fare tier that includes changes. - Airport add-ons: tight connections can trigger meals, transport, or a hotel night.
Tip: a slightly higher fare with a better connection can be the real bargain.
When a “basic” ticket is a good deal, and when it will backfire
A basic ticket works well when your trip is simple.
Good deal example: You’re doing a long weekend in Lisbon with a single backpack. You don’t care where you sit, and you won’t change dates. A hand-luggage-only fare can be a clean win.
Backfire example: You’re flying with kids, you need checked bags, and you want seats together. The cheapest base fare plus bags plus seats can cost more than the “standard” fare that bundles them. You also lose time and patience during checkout because every click becomes a decision.
A smart rule: if you already know you’ll pay for one checked bag and seat selection, compare that total against the next cabin fare up. On many low cost airlines international flights, the bundle ends up cheaper than piecing it together.
Best low cost airlines international flights for Brazil to Europe in 2026 (routes, fees, and who each airline fits best)
For Brazil to Europe in 2026, the lowest prices often come from network airlines offering basic fares, not from classic short-haul low-cost carriers flying the whole way.

Schedules, nonstop status, and add-on fees change by season and by fare type. Always verify route availability, baggage, and seat rules on the airline website before you book. Treat the examples below as a shortlist for comparison, not a promise of pricing.
Comparison table, 10 airlines, cheapest nonstop style routes, typical baggage fees, best for families or solo travelers

Fast picks by trip type, backpack only, one checked bag, traveling with kids, and last minute trips
Backpack only (personal item or light carry-on):
You’ll often do best with hand-luggage-only fares on major carriers into Lisbon or Madrid, then decide if you need a low-cost intra-Europe add-on. This is where low cost airlines international flights can truly shine, because you’re buying almost nothing extra.
One checked bag:
Look for fares that bundle the first checked bag. TAP Air Portugal and Air Europa often price well when you step up from the absolute lowest fare and include baggage from the start.
Traveling with kids:
Nonstop helps. TAP Air Portugal and Air Europa can be a strong fit for families because they often offer workable nonstop options and more traditional long-haul service, even when you buy a cheaper fare class. You still need to price seats together early.
Last-minute trips:
Last-minute “cheap” can be rare on long-haul. You’ll usually win by being flexible with airports (GRU vs GIG, or Lisbon vs Madrid) and accepting one stop, as long as the connection is safe and on one ticket.
If you want a quick benchmark for what’s available on your dates, TAP publishes deal pages that can help you sanity-check routes from Brazil, then you can compare against other carriers for the same week. Start with TAP’s cheap flights from Brazil and verify the exact fare inclusions before buying.
How to find cheap international flights without getting stuck with bad layovers or big fees
Cheap long-haul tickets aren’t found by luck. You find them by running the same process every time and refusing to ignore add-on costs.
The goal is to compare like-for-like totals: flight price plus bags plus seats plus the connection risk. A “cheaper” ticket that forces a long overnight layover can quietly cost more once you add meals, airport transfers, and a hotel.
A simple search workflow, flexible dates, alerts, and total price math
Use this repeatable workflow:
- Start with flexible dates
Search a whole month view when you can. Prices on Brazil to Europe routes can swing a lot by day of week and season. - Check nonstop versus one stop first
Nonstop often costs more, but it can remove risk and airport costs. One stop can be great when it’s on one ticket with a sensible connection. - Set price alerts
Price alerts help you avoid panic booking. Use a tracking tool like Google Flights to watch routes and spot patterns, then buy on the airline site once you’re ready. - Do the total-price math before you commit
Open the booking page and add what you’ll actually use: carry-on, checked bag, and seats. If you’re traveling as a pair or family, price seats together. Write down the total and compare it against the next fare tier. - Confirm the rules where it matters
Always confirm baggage size, weight, and fare change rules on the airline site for your specific fare name, not a blog summary.
Red flags to avoid, separate tickets, tight connections, and strict baggage rules
Some cheap itineraries are cheap because risk is pushed onto you. Watch for these:
Separate tickets and self-transfer connections
If your first flight is late and you miss the second, the second airline might treat you as a no-show. That can mean buying a new ticket at walk-up prices. For long-haul, one-ticket itineraries are safer.
Tight connections at big hubs
A short connection looks efficient on paper. In reality, you may need passport control, security re-screening, or a terminal change. Give yourself breathing room, especially with kids or checked bags.
Strict baggage rules on the “cheap leg”
A low-cost European connection can be where the trip gets expensive. If your long-haul fare includes a cabin bag but the short-haul leg does not, you may end up paying at the gate.
Transit entry rules
Some routes require transit checks even if you don’t leave the airport. Confirm transit rules for layover countries before you lock in the itinerary, and re-check close to departure since rules can change.
Conclusion
You can save real money on low cost airlines international flights when you treat the ticket like a menu, not a bundle. The winning move is simple: compare the total cost after you add the bags, seats, and connection risk you can’t avoid.
Your short action plan: choose a date range, compare nonstop versus one stop totals, confirm baggage and seat rules on the airline site, then book when the final price makes sense. Prices, routes, and fees change often, so verify everything again right before you fly, especially baggage size limits and check-in requirements. If you stick to total cost thinking, the “cheap fare” stops being a gamble and starts being a tool you control.
