Luxair Carry-On Rules: 6 kg Limit & Size Guide (2026)

Luxair (IATA: LG) is Luxembourg's national airline, state-controlled and operating since 1961. Flying from Luxembourg Findel Airport (LUX), Luxair serves a European network of leisure and business destinations including the Canary Islands, Mediterranean coasts, Portugal, Greece, and European capitals. There is no long-haul operation — Luxair is purely a European carrier, catering both to Luxembourg's business traveller community and a substantial leisure segment through its LuxairTours package holiday division.

Despite being a full-service airline that includes checked baggage on most fares, Luxair imposes a 6 kg carry-on weight limit and a 35 cm width restriction that is narrower than most European airline standards. These two figures — 6 kg and 35 cm — are the defining features of Luxair's carry-on policy and the ones most likely to catch passengers off-guard.

Luxair Carry-On Allowance at a Glance

Cabin / Fare	Carry-On Bag	Personal Item	Weight
Economy	55 × 35 × 20 cm	Under-seat bag	6 kg
LuxairClub (Business)	55 × 35 × 20 cm	Under-seat bag	10 kg

Economy Carry-On Bag

Luxair Economy passengers are permitted one carry-on bag for the overhead locker:

• Maximum size: 55 × 35 × 20 cm (length × width × depth)
• Weight limit: 6 kg
• Personal item: One additional small item (laptop bag, small handbag) permitted under the seat

Both the weight limit and the width limit deserve attention before you pack.

The 6 kg weight limit is notably strict for a full-service carrier. Many airlines in the same category — Austrian Airlines, SAS, Finnair — allow 8 kg or more. Luxair's 6 kg effectively matches some low-cost carriers, despite including checked baggage in most fares. A 13-inch laptop alone weighs approximately 1.3–2 kg. Add a power adaptor, a set of headphones, and a light change of clothes, and you are already at 4–5 kg. Passengers carrying standard laptop bags for business travel should weigh their kit before arriving at the airport.

The 35 cm width limit is the other critical number. Most carry-on luggage marketed as fitting European airline standards uses the IATA recommended maximum of 56 × 45 × 25 cm, or common variants around 55 × 40 × 20 cm. At 35 cm, Luxair's width allowance is 5 cm narrower than the 40 cm many travellers assume. Popular carry-on suitcases — including many 20-inch models and standard cabin-size rolling bags — are wider than 35 cm and technically do not comply. Check your specific bag's dimensions against Luxair's 35 cm figure rather than assuming any carry-on will fit.

LuxairClub (Business) Carry-On

LuxairClub passengers (Luxair's Business Class cabin) receive:

• Maximum size: 55 × 35 × 20 cm (same dimensions)
• Weight limit: 10 kg — compared to 6 kg in Economy
• Personal item: Under-seat item permitted

The 10 kg allowance provides meaningful additional flexibility, though the 35 cm width restriction remains unchanged across all cabins.

LuxairClub members and frequent flyers in the LuxairClub loyalty programme also receive an extra checked bag weight allowance and priority boarding, securing access to overhead bin space before Economy passengers board.

Personal Item

Luxair permits one small personal item in addition to the overhead carry-on. This must fit under the seat in front of you. Acceptable items include laptop bags, small handbags, and camera bags. Luxair does not publish a separate size limit for the personal item, but it should be compact enough to sit under the seat without obstruction.

If travelling Economy with a laptop, one practical approach is to carry the laptop in a slim under-seat bag and pack clothing and other items in the overhead carry-on — this keeps total weight in check and keeps the laptop accessible throughout the flight.

Enforcement at LUX

Luxair is known for strict weight enforcement at Luxembourg Findel Airport. LUX is a small, well-organised airport with straightforward processes, and the compactness of the facility means that staff consistently apply the carry-on policy rather than waving bags through when queues are long.

At check-in, bag weighing for carry-on items is not universal on every flight, but occurs regularly. Gate agents enforce weight limits on full flights or when bins are expected to be at capacity. The enforcement profile sits closer to that of a low-cost carrier than to a permissive full-service airline in terms of how consistently the 6 kg limit is applied.

Arriving at the gate with a bag clearly over 6 kg risks being directed back to check-in, where adding checked baggage at the airport is significantly more expensive than pre-purchasing it online. If your bag is borderline, weigh it at home.

LuxairTours Package Flights

Luxair operates a major package holiday and tour division — LuxairTours — which accounts for a significant share of Luxair's passenger volume. LuxairTours packages cover Canary Islands, Mediterranean, North Africa, and Atlantic destinations (Madeira, Cape Verde).

For flights operated by Luxair under the LuxairTours brand, the same carry-on rules apply: 55 × 35 × 20 cm, 6 kg for Economy. Check your tour documentation to confirm the operating carrier — some LuxairTours packages use wet-leased or charter aircraft at peak season, and allowances may occasionally differ. If Luxair is the operating carrier, standard Luxair carry-on policy governs.

Fleet Notes

Luxair operates Boeing 737-700 and 737-800 aircraft on its main leisure routes. Overhead bins on these aircraft are standard-sized and accommodate compliant carry-on bags without issue. Shorter European routes may use Bombardier Q400 turboprops, which have smaller overhead bins — a situation similar to the ATR 72 at Air Serbia or the Dash 8 at Austrian. On Q400 routes, particularly compact overhead space may mean some bags need to be gate-checked even if they comply with size requirements.

If your Luxair route involves a smaller aircraft, check the booking for aircraft type.

Tips for Luxair Passengers

Measure your bag's width, not just its height. The 35 cm width limit is the spec most likely to catch out passengers who own standard 40 cm-wide carry-on bags. Don't assume your usual travel bag complies — check the width.

Weigh everything before you leave home. Six kilograms is tight for a carry-on that includes a laptop and charger. Use a luggage scale at home rather than guessing. If your bag is at 5.8 kg empty with clothing, you are over before you add your laptop.

LUX is a very small, very manageable airport. Security queues are short outside peak periods, and the terminal is compact. There is no need for the extended buffers required at Heathrow or Frankfurt — but do not use this as an excuse to run late to check-in, as Luxair's check-in desks do weigh bags.

Business class upgrading is worth considering for heavy packers. If your carry-on routinely approaches 8–10 kg and you need items in the cabin, LuxairClub's 10 kg allowance is a meaningful difference. Evaluate the upgrade cost against the checked bag fee if you would otherwise need to check items.

Pre-purchase checked baggage if you expect to be over 6 kg. Economy fares generally include 23 kg checked baggage on Luxair, so if you cannot fit what you need into 6 kg in the cabin, use the hold allowance. There is no penalty for using your included checked bag — the issue only arises if you attempt to bring an oversized or overweight bag onboard without checking it.

Confirm LuxairTours terms at booking. If you are purchasing a package rather than a direct flight ticket, verify the carry-on allowance in your package documentation to ensure it matches standard Luxair policy.

The Bottom Line

Luxair is a full-service European carrier that operates with carry-on rules closer to a low-cost airline in terms of weight: 6 kg in Economy, 10 kg in LuxairClub, both limited to 55 × 35 × 20 cm. The 6 kg weight limit and the 35 cm width restriction are consistently enforced at Luxembourg Findel. Most passengers arriving with standard carry-on bags purchased for Ryanair or easyJet compliance may still be within size on Luxair, but weight will be the binding constraint. Weigh your bag before travel, confirm your bag's width against the 35 cm limit, and use the included checked baggage allowance for anything that won't comfortably fit within 6 kg in the cabin.
