Greek tourism is on course for a strong summer season in 2026, with the latest airline seat capacity data pointing to sustained demand from Greece’s traditional European markets and a marked lengthening of the season into the shoulder months.
According to the INSETE Intelligence Airdata Tracker’s latest figures, covering week 33 of the year, total seat capacity on inbound international flights for the 2026 summer season stands at 30,657,811 — up 7.6% on 2025.
Of that total, 14,112,817 seats, or 52.6%, relate to the remainder of the season still to come.
August leads the monthly breakdown with 5,702,497 seats (18.6% of the total), narrowly ahead of July with 5,624,885 (18.3%). September follows with 4,806,946 seats (15.7%), June with 4,729,552 (15.4%), May with 3,723,874 (12.1%) and October with 3,603,474 (11.8%).
At the start of the season, April recorded 2,273,081 seats (7.4%) and March 193,602 (0.6%).
While July and August remain the dominant months, the year-on-year comparison points to a notable structural shift: March posted by far the sharpest percentage increase, up 68.2%, with October also up strongly, by 19%.
Growth in the peak summer months was more modest by comparison, though still consistent, ranging between 5.8% and 6.6% — evidence, the data suggests, of airlines and tour operators extending the season at both ends.
By source market, the UK and Germany remain firmly dominant, together accounting for the bulk of scheduled capacity.
The UK leads with 6,168,016 seats, up 9.3%, followed by Germany with 5,195,540, up 6.6%. Italy rounds out the top three with 2,713,074 seats (up 7.9%), ahead of France with 1,847,386 (up 2.4%), the Netherlands with 1,274,107 (up 6.9%) and the United States with 741,568 (up 2.1%).
The strength of the UK and German markets is even more pronounced looking ahead: for the remainder of the season, available seats from the UK stand at 2,820,324, up 10.5% on 2025, with Germany at 2,507,266, up 10.4%.
