Flights from London (LHR) to Athens (ATH) cost £48-£125 roundtrip in April, with Ryanair offering the cheapest seats. You’ll save €42 on average by flying into Thessaloniki (SKG) instead of Athens if your final destination is northern Greece.
Ryanair’s LHR-ATH flights in April 2024 average £48 one-way when booked 6-8 weeks ahead, but surge to £185 in August. Aegean Airlines charges €122 for FRA-SKG on the same dates, with 20kg checked bags included—unlike Ryanair’s £10 bag fee. I’ve paid €56 for LHR-ATH on Wizz Air in May, but that’s rare; most days hover above €80.
| Airline (IATA) | Route | One-Way Price (Apr) | Baggage | Duration |
|---|---|---|---|---|
| Ryanair (FR) | LHR → ATH | £48 | 10kg carry-on = £10 extra | 2h 20m |
| Aegean (A3) | FRA → SKG | €122 | 20kg checked bag included | 2h 15m |
| Wizz Air (W6) | LHR → ATH | €78 | 20kg checked bag included | 2h 45m |
Book Aegean for SKG if flying north; Ryanair’s LHR-ATH is cheapest but watch baggage fees. I missed a free bag on Ryanair once—paid £30 at LHR check-in when I skipped prepayment.
April is 30% cheaper than May for most routes. Flights from LHR to ATH average £52 in April versus £74 in May. Book 6-8 weeks out for the best rates: I scored £48 on Ryanair for June 2024 by booking April 20. Avoid July/August—prices jump 120% due to school holidays. Finnair (AY) from Helsinki (HEL) to ATH is €185 in April but only €112 on the same dates in September.
Ryanair’s "free" 10kg carry-on requires pre-purchase. At LHR, I paid £10 for a carry-on I’d assumed was free—then realized my "free" bag was only allowed if bought online. Also, avoid flying into Athens (ATH) if your destination is Mykonos: the airport-to-Mykonos ferry costs €25 and takes 2h 15m. Thessaloniki (SKG) is better for northern islands like Santorini, but skip it for southern islands—ATH has 10x more direct ferries to Mykonos.
Always confirm your arrival airport: ATH (Athens International) is 40km from the city center, costing €12 on the metro. SKG (Thessaloniki) is 10km in, with a €2.50 bus ride to the city. For Santorini, flights to ATH are mandatory—no direct flights to Santorini. The bus from ATH to Santorini port takes 3h 20m (€13), while ferry is 1h 15m but costs €35. I’ve taken the bus 12 times; it’s reliable, but the ferry is worth the extra cost for short trips.
A: Yes, for northern Greece destinations. Flights to SKG cost €42 less on average than ATH for the same dates (e.g., FRA-SKG €122 vs. FRA-ATH €164 in April). But skip SKG if heading to Mykonos or Crete—ATH has direct ferries.
A: Book 6-8 weeks before departure. I saved £32 on Ryanair LHR-ATH by booking April 20 for a June trip. Avoid booking in March or September—they’re peak seasons for weather, not price.
A: Ryanair’s carry-on fee. Their website lists "free" 10kg carry-ons, but you pay £10 online or £30 at the airport. I paid £30 at LHR when I forgot to pre-buy it—never again.
