You can't. I mean, you can check flightradar24.com to see what's been used for the past few days. But the assumption underlying your question -- that there is some plane or set of planes allocated to that, or any, route -- is false. They could use a NEXT plane today and a non-NEXT tomorrow, or vice versa. And they could plan to use a NEXT plane today, only to swap it out an hour prior to departure.
