If Delta or United run a domestic route with a mix of recliner and lie-flat flights, is there any easy way on google flights or matrix ita to filter by just the lie-flat flights to see if a lie-flat has good pricing? Rght now I have to click through each flight offered to see the seating on it on google flights. I'm okay-ish with matrix ita advanced code usage, not super advanced so wonderng if someone else know how to.

I understand there might be a long-term aircraft swap
