I have been trading stocks for years but new to options, if i want to bet against Delta Air Lines?

And trade them on options, and i’m looking at the puts, which do I trade? I’m very confused.

You should not trade them at all until you are no longer confused……..one has to know what they are doing going in and when they are getting out…….
I would stay away from the airlines completely in long term trades…….
How do you like it when people use all these terms and dont explain anything? me either
