BA put spread

Looking for $BA to stay in its trading range with 310 at the bottom. Stock is in its second big down day (almost 5% since Friday) but it looks like the big volume is starting to wane. I’m admittedly early but there’s enough room here, with the stock at 328.63, that I feel comfortable with it.
Sold $BA May 18 310/300 BuPS for 1.34.
