What’s the biggest aviation-geek event of the year? MegaDo, of course, which over the years has built a reputation as the event for people who adore commercial aviation. This year, the 2019 MegaDo featured a Star Alliance theme, and took place on the ground and in the skies of Germany and Croatia over the course of five days last week.The organizers of MegaDo gave TPG U.K. tickets to attend along with one of our readers. On day one, our lucky competition winner Peter Brownlees and I found ourselves meeting at Frankfurt Airport, excited about an itinerary that promised behind-the-scenes events and experiences with airlines — and even a flight on our very own chartered Airbus A320.MegaDo is especially popular in the U.S., but this year’s attendees travelled from as far as Brazil, Australia, China, India and Singapore.The first two days saw events, presentations and focus groups in Frankfurt by representatives from Marriott, Star Alliance, Frankfurt Airport and a number of airlines. Attendees also got to tour a Lufthansa Boeing 747-8, a Singapore Airlines A380 and a sneak preview of the new Terminal 3 at Frankfurt Airport. And then we got our very own Airbus A320, chartered from Croatia Airlines.TPG UK competition winner Peter Brownless and I geeking over the Croatia Airlines A320.

Excitement built up the night before when MegaDo attendees successfully tracked the movements of our A320 and her inbound journey to Frankfurt via FlightRadar24. It was a gathering of 106 aviation enthusiasts after all.Though not quite in the league of some VIP charter aircraft, the A320 was ours for the day, which meant that it wasn’t quite your standard short-haul flight. We had access to the aircraft before, during and after flights to geek out. Service was most definitely a notch above normal, and three auction winners got the chance to sit in the cockpit for takeoffs in Frankfurt and Hamburg as well as the approach into Dubrovnik.In case you are tempted to do this yourself, a chartered A320 will likely set you back $65,000 for the day!After the hour-long flight to Hamburg, we were treated to a tour of the Airbus facilities in the German town, including the assembly line of the Airbus A321.(Photo by Christian Kramer/The Points Guy)Fuselages of the A350 ready for assembly.

Lunch on board this two-hour flight was served by the Croatia Airlines crew, though other attendees added to the inflight service, including a round of German schnapps.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.

Upon arrival, we were greeted with a water cannon salute at the airport, as well as a drinks reception hosted by Croatia Airlines in the now-vacant former terminal building.(Photo by Christian Kramer/The Points Guy)The old, unused terminal at Zagreb Airport.

Attendees were treated to both a tour of the new terminal at Zagreb Airport as well as the Croatia Airlines maintenance facility, which is used by a number of other airlines.Zagreb airport’s baggage handling facilities.

I for one, am looking forward to MegaDo 2020.(Photo by Christian Kramer/The Points Guy)
