I had quite good experiences on flights so far but also stumble across a flight menu with sometimes not even a vegetarian option. This seems to depend on the airline, cheaper ones tend to offer just the ordinary stuff without any compassionate and healthy alternatives.
On my last flight, we had issues pre-booking some meals beforehand and expected to stay hungry during the flight. But the amazingly friendly steward took up the challenge and collected raw vegan items from the crew's meal selections and put together a beautiful meal for us. There are so many generous and loving humans out there - I am full of gratitude for such experiences. 💚
