I've just had a two part flight, Antalya-Istanbul-London Gatwick via Pegasus airlines.
I arrived at the airport early and checked in with plenty of time to spare. The boarding for the first part of the flight, Antalya-Istanbul was 30 minutes late, so the flight also left 30 minutes late, but I don't think this is seen as a delay in Turkey.
This meant that when I finally got off the plane, my next plane was supposedly in the boarding stage (according to my ticket). All I had to do was proceed straight to passport control, but unfortunately, whilst I was queued up and almost through, the systems for passport control went down for a good 20-30 minutes all over Turkey. I was told that nothing could be done about it and that I would most likely miss my flight, which of course I did (if only that flight also left 30 minutes late). Pegasus airlines stuck me on a flight to London Stansted to make up for it (the next London flights would have been a day later), but this was six hours later.
I was offered no food or drink and had to pay for overpriced airport supplies myself, and ended up taking a late night train to crawl home once I did land. As luck would have it, my flight to London Stansted had yet another boarding time that was late by 45 minutes, so the flight was also delayed (again, I'm not sure if Turkey views it as such). I was also wrongly told that my luggage would end up in Gatwick, but the lovely people at Stansted put in some work and found that my luggage was actually taken off the plane and came to Stansted with me.
Is there any compensation that I can claim for this whole thing?
TL;DR: Can I claim compensation for two delayed flights, one missed flight, almost walked away without luggage, and a boatload of stress?
