By flights (25) and nights (56), my busiest travel year ever! Driving a lot of that was a change of employment: I've joined the ranks of flying commuters by taking a year-long secondment to Aer Lingus, with monthly trips to Ireland from my home in the UK.

Some stats, new entries for 2025 marked in bold:

Airports: AMS, BHD, BRS, CDG, DUB, EXT, GCI, HEL, ICN, IST, LGW, LHR, LJU, TBS, TLL, VRN
Airlines: Aurigny, BA Euroflyer, British Airways, Emerald Airlines, Finnair, KLM Cityhopper, Nordic Regional Airlines, Turkish Airlines
Aircraft: Airbus A320, Airbus A321, Airbus A350, ATR 72, Embraer E175, Embraer E190

I wrote a trip report celebrating my first 'novelty flight' (new airline, aircraft, and airports) in over a decade - little could I know that 2025 would feature a dozen departures on the then-unfamiliar ATR72. Those 97 mile Exeter - Guernsey flights were my shortest ever - for all of 3 months, when (like Fabo.sk ) I took the 63 mile Tallinn - Helsinki service. Technically I went one better with what should have been my final flight of the year, which due to mechanical issues ended up operating from Dublin to... Dublin, for zero miles of progress (but despite getting nowhere, I spent more time in the air than during the HEL hop).

At the other extreme were flights between Helsinki and Seoul: 4381 great circle miles, but much longer in reality thanks to the polar routing. I did the outbound in business class - trying Finnair's curious no-recline "AirLounge" for the first time - which was quite the contrast to all my regional economy flying! In other avgeekery, I was on BA's inaugural flight out of Tbilisi (also in business).

Countries: Turkey, Georgia, Italy, Slovenia, Belgium, Germany, Czech Republic, Denmark, Sweden, Finland, Estonia, France, South Korea

Setting foot in 15 countries, with 6 of them being for the first time, were both personal records. Admittedly some of these were minimal visits, and Denmark was just a transit, as I made my way from London to Tallinn by rail and sail as part of the Baltic Brutal lupine race (you can find my experiences mixed in with the larger trip report). As a warm-up for that I also tackled Garda to Ljubljana by train, which got written up on my blog; the Korean trip, meanwhile, is thus-far only documented on polarsteps. Balancing all that breadth was an in-depth trip to the Channel Islands: I'm amused that I spent five hours in Prague, yet five days on Sark!

Like Nimrod1965 I also bid farewell to GWR's HST "castle" trains, although as an observer rather than a rider. Here's the very last service out of my local station, Exeter St Davids, on a misty December morning:
