Was there anything special about your flight? For example, late inbound arrival, last minute equipment swap, or, I know you may not be aware, any weight and balance issue affecting your flight?

The standard practice is to load priority bags last so that they get unloaded first, but due to the reasons mentioned above, priority bags may not be able to get loaded first or unloaded last.

My flight had a mechanical issue once that resulted in a last minute equipment swap, and all priority bags were unloaded last.
