1st interview, list every single charge and note that they were dropped. Specify exactly what you were "convicted" of.
If that doesn't work, I might try the next company with only what was not completely expunged.
The best thing you can do is be completely upfront and 100% honest. You need to be aware though, that your past incidences will make your future in the airlines pretty doubtful. I do recommend you try to apply, and believe your upfront and honest notification may be your best approach.
