Flying on DL45 from Dublin to JFK soon. On Delta airlines website it says I'm on A330-300 but it used to say 767-400. Using this site (https://www.flightradar24.com/data/flights/dl45) shows all previous flights were on a 767-400.
I paid for an upgraded seat and I'm concerned if the seat plan is different between the 767-400 and A330-300, so I'm unsure if my upgrade will carry over. Any suggestions?
Also, when searching "DL45 which plane" it states: 'DL45 is a Delta Air Lines flight from Dublin to New York . The flight has a distance of 5108 km (3155 mi.) with an average flight time of 7h 54m. It is operated on a daily basis using Boeing B767-400 Planes.'.
How does it work with the seat plan, giving that each plane houses a different number of passengers? And what do I go off of? The airline website or other sites I am seeing?
