Turkey has seen the strongest revival in flights since the pandemic as airlines prepare for a busy summer peak.
Greece has seen the second highest level of recovery in departures from UK airports this month against July 2019, according to aviation data firm Cirium.
Overall departures are set to reach 89% of the same month pre-Covid with 92,404 flights equating to more than 16.5 million seats.
This month is forecast to see the highest number of UK departures since October 2019, as the post-pandemic recovery continues, Cirium confirmed.
Scheduled UK departures are up 11% compared to July last year and up 149% compared to May 2021, as travellers resume business and leisure trips.
Dublin remains the most popular international destination by scheduled flights, followed by Amsterdam, Palma, Malaga and Faro.
The summer holiday destinations showing the highest level of recovery are Turkey (up 47% to 3,586 flights over July 2019), Greece (up 33% to 4,960) and Morocco (up 15% to 424).
Growth has also been seen to Croatia, Portugal and the US.
Spain dominates as the top destination this month with 14,091 flights, although the total is down by 6% on July 2019.
Italy and France also continue to see high levels of flights from the UK but numbers are down by 13% to both countries.
Malta has suffered the steepest decline, with departures from the UK down 22% to 424.
The new figures were released and the industry waits to discover if Eurocontrol workers will carry out a threat to carry out a wave of strikes this summer.
