AirTags are very useful. Not for reuniting you with lost luggage any more quickly (nothing can do that, I’m afraid), but if you do land in Delhi and see that your bags are still in Amsterdam, you can at least file a report straight away without waiting for goodness knows how long at the baggage carousel.

That said, my general advice at the moment would be to travel with hand baggage only if you can. My travel is split between AF/KL and BA/AA, and the only hub through which I’m more or less relaxed about checking bags at the moment is CDG.
