Are planes from LAX to EWR in the United Fleet usually airbus a319's or airbus a320's? If this is true, which planes have the ability to pipe in ch 9 on their planes? I know the 737's can't do it, but can the a319's and a320's do it? I know I'll be taking flight later on in the near future and I wanna kinda know if it's worth the ask considering the type of plane. Is it true that if I get a 757 on that route, that would be an old continental plane, because I know that those 757's which are continental planes cannot do it either. The only planes that can do it, I think, are the United 757's and the 767's and I'm unsure about the airbuses. Just trying to cover the bases so I don't need to ask a question closer to my trip to give people some time to answer.
If there is a particular person, here on the forum, who is really knowledgeable about these united ch 9 topics, it might just be easy to PM me, but if you want the answer to be seen by everyone, you can reply here as well. Hope everyone is enjoying the beginning of their summer and I wish everyone a good day.
