I've worked so hard on this airplane (and it's decent not the best or worst) I've worked so long that I want to tease it but not spoil it. Below are some hints to help you guess what the plane is. Cheers to the person who gets it

My lucky number is 7
Why 4 engines? 2 sounds alot better
I've been in some trouble recently but I should recover
I'm one of the most popular jets ever
And there is a bus that is competing with me

What plane am I?

Don't worry if you don't get it! I probably won't get it either. Anyways stay tuned for the post
