On the cheapest SKY Joy or SKY Offer fare — the price you actually book when you grab a Sky Express deal — you get exactly one cabin bag (up to 8 kg, 55 x 40 x 23 cm) plus one small personal item (40 x 30 x 15 cm) that has to slide under the seat. That’s it. There is no checked bag on these fares: a hold bag is an add-on that starts from about €15 and climbs fast if you leave it to the airport counter.
This is the trap on Greek island hops. Sky Express prices look great because they’re stripped to the cabin bag, and the Greek-domestic crowd often packs heavy for a week on Crete or Santorini. If you need to put a bag in the hold, you want one of the bundled fares (SKY Joy+ with 15 kg, SKY Enjoy with 23 kg) or to pre-pay the bag online — never at the gate, where it’s roughly double.

What you actually get on a cheap fare
What you actually get on a cheap Sky Express deal fare: one 8 kg cabin bag and one under-seat personal item, full stop. The cheapest SKY Joy and SKY Offer fares strip the hold bag entirely, so a deal headline price is a cabin-only price. The cabin allowance itself is generous for an island carrier (8 kg and a roomy 55 x 40 x 23 cm), so a carry-on-only traveller can fly these fares and pay nothing extra.
If you need a hold bag, budget for it up front and add it online: a checked bag runs from about €15 (domestic) and into the €30–€45 range internationally, and the airport counter is roughly double. If you’re already going to pay for 23 kg, compare the price of upgrading straight to the SKY Enjoy bundle, which folds the 23 kg bag in — it can come out cheaper than buying the bag as an add-on, especially on heavier international routes.
Oversize, sports & special items
Sports equipment is priced by size rather than weight: medium items up to 150 cm (skis, a bike box, a small surfboard) run around €50, and large items up to 250 cm around €90. Large musical instruments that need their own handling are about €40; a smaller instrument that fits the 55 x 40 x 23 cm cabin limit travels as your cabin bag. Oversize or overweight items must be declared in advance — don’t show up at a small island gate hoping to wing it.
For 2025/2026, the personal item stays a strict 40 x 30 x 15 cm under-seat size and the cabin bag holds at 8 kg / 55 x 40 x 23 cm on economy fares — in line with the tightening EU cabin-baggage norms, so don’t assume a bigger roller will pass. As always with Sky Express, the cheap fares are cabin-only by design; the bundled SKY Joy+/Enjoy fares exist precisely so you pay only for the hold allowance you actually need.
Frequently asked questions
Does the cheapest Sky Express fare include a checked bag?
No. SKY Joy and SKY Offer, the cheapest economy fares, include only an 8 kg cabin bag plus an under-seat personal item. A checked bag is a paid add-on starting from about €15.
What is the Sky Express cabin baggage allowance?
One cabin bag up to 8 kg and 55 x 40 x 23 cm in economy (up to 13 kg in BLISS business), plus one personal item up to 40 x 30 x 15 cm that must fit under the seat. Both are free on every fare.
How much does a checked bag cost on Sky Express?
Booked online, a 15 kg bag is roughly €15–€40 and a 23 kg bag roughly €20–€45 depending on whether the route is domestic or international, plus the date and channel. At the airport it’s significantly more — you can save up to 50% by paying online.
Which Sky Express fare includes a 23 kg checked bag?
SKY Enjoy includes 1 x 23 kg. SKY Joy+ and SKY Basic include 1 x 15 kg, while business BLISS and BLISS+ include 2 x 32 kg.
Can I add a bag after booking?
Yes. You can add checked baggage or extra weight through Manage My Booking up to 3 hours before departure, and it’s cheaper than buying at the airport counter.
How much is excess weight on Sky Express?
Excess weight is about €5–€8 per kg if you pre-pay online and around €7–€10 per kg at the airport. It’s almost always cheaper to add the next bag tier than to pay per-kilo overweight at the gate.
What does Sky Express charge for sports equipment or instruments?
Sports gear is priced by size: about €50 for medium items up to 150 cm and about €90 for large items up to 250 cm. Large musical instruments run about €40; small instruments that fit the cabin-bag size travel as your carry-on.
Is the Sky Express personal item really under-seat only?
Yes — the free personal item is capped at 40 x 30 x 15 cm and must fit under the seat in front of you. If you need a larger bag in the overhead, that’s the 8 kg cabin bag, which is included anyway on standard economy fares.
