Airline-by-airline comparison (2026)

Ryanair & Wizz Air — the price leaders

Typical fare 2026: £50-£110 return off-peak, hand-luggage only. Pros: The lowest headline fares — sometimes under £50 one-way in shoulder season. Good frequency from London's budget airports. Cons: Cheapest fares are cabin-only; a larger cabin bag, hold bag and allocated seat all cost extra. On a near-4-hour flight, the comfort trade-off is more noticeable.

British Airways — the frequency leader

Typical fare 2026: £120-£220 return; "Basic" fares are cabin-only. Pros: The most flights on the route (around 39 a week), Avios earning, a bag on standard fares, schedule flexibility. Cons: Higher headline fare than the budget carriers.

Aegean — the Greek flag carrier

Typical fare 2026: £110-£200 return; standard fares include a bag. Pros: Well-regarded full-service product, a checked bag and snack included, better legroom, and seamless domestic connections to the islands. Cons: Pricier than the budget carriers on headline fare — though the gap narrows once you add a bag to a budget fare.

easyJet & Jet2

Typical fare 2026: easyJet £70-£150; Jet2 with baggage included from the regions. Pros: Useful frequencies and regional coverage; Jet2 for a baggage-included leisure option. Cons: easyJet's cheapest fares are cabin-only.

The honest read: hand-luggage only, Ryanair or Wizz win on price. For a bag, a fuller service or onward island flights, Aegean or BA are often better all-in value than they look. Jet2 suits regional beach-holiday travellers.

UK airport comparison — fly local

Athens is served from a good spread of UK airports, so the cheapest option is often your nearest one. London (Heathrow, Stansted, Luton, Gatwick) has the most choice, but Manchester, Edinburgh, Birmingham and Bristol also have direct service, mainly spring to autumn. For regional travellers, always price your local direct flight before assuming a cheap London fare wins once the London trek is added.

Price bands by month for 2026

Round-trip economy, UK to Athens, one adult. Representative ranges to plan against, not live quotes.

The pattern follows the usual UK-holiday shape — see our cheapest month to fly from the UK roundup — with spring and autumn standing out as the best value for Athens' most comfortable sightseeing weather (mid-summer is intensely hot in the city).

Island-hopping from Athens

Athens is the main hub for the Greek islands, which is a big reason it's the most-searched Greece flight destination:

• Domestic flights — Aegean and Sky Express connect Athens to Santorini, Mykonos, Crete, Rhodes and more, often on the same ticket as your Aegean international flight.
• Ferries — the port of Piraeus (reachable by Metro line 3 from the airport and city) serves the Cyclades (Santorini, Mykonos, Naxos, Paros) and the Saronic islands.

Many travellers spend a day or two in Athens for the Acropolis and ancient sites, then continue to the islands — fly into Athens and plan the onward leg from there.

Baggage compared, honestly

The rule that saves the most: add any hold bag at booking, never at the airport, and compare the all-in price. A £60 Ryanair fare plus a £45 return hold bag is £105 — which can approach an Aegean fare that already includes a bag, a snack and island connections. Compare the total, not the headline.

The booking windows that actually save money

• Off-peak months (Jan, Feb, Nov): Book 6-10 weeks out.
• Summer (Jul-Aug) and Easter: Book 8-12 weeks out — peak demand, fares only rise. Note Greek Orthodox Easter can differ from Western Easter.
• Spring/autumn peaks (Apr-Jun, Sep-Oct): Book 6-10 weeks out for the best sightseeing weather.
• Weekend breaks: A Thursday or Saturday departure often undercuts the Friday-evening rush.

Set a price alert for your dates and book when a budget carrier drops a sale fare.

Entry rules for UK travellers in 2026

• No visa for stays up to 90 days in any 180-day period across the Schengen area.
• A passport issued within the last 10 years and valid for at least 3 months after your planned departure from Schengen — both enforced at the border.
• ETIAS travel authorisation once the scheme launches in 2026 — check the current status before you travel.
• UK travellers use the e-gates at Athens where available.

Always check the UK government's Greece travel advice shortly before you fly.

Athens Airport to the city centre

Athens International Airport (ATH, Eleftherios Venizelos) is well connected. The Metro (line 3) runs from the airport to Syntagma Square in about 40 minutes, and the reliable X95 express bus runs 24 hours to the centre. A taxi has a fixed daytime fare to the city. Metro line 3 also continues to the port of Piraeus for island ferries. The Metro is the best value for most travellers. Once you've sorted the flight and transfer, our best Athens hotels 2026 guide covers where to base yourself.

Common mistakes UK-Athens travellers make

1. Sightseeing Athens in peak summer heat. July-August often tops 35°C — spring and autumn are far more comfortable and cheaper.
2. Routing through London unnecessarily. Athens flies direct from Manchester, Edinburgh and more — your local one may be cheapest.
3. Judging budget fares on the headline price. A £60 Ryanair fare plus a £45 hold bag can approach an Aegean fare that includes one.
4. Not planning the island leg. If you're island-hopping, sort the domestic flight or Piraeus ferry before you go.
5. Adding baggage at the airport. Always add it online at booking.
6. Assuming an old passport is fine. The Schengen 10-year issue rule catches UK travellers out.
7. Forgetting Greek Orthodox Easter. It's a major domestic travel period and can spike demand on different dates from Western Easter.
