Uh, no there wont be a 321 or any varient in their fleet but there will be a new entry, its called the MOM. UA has already said they want to be the launch customer and it fits within their time frame.
If UA really wanted any of the 321 series, they would have ordered them by now. Plus dont forget the AA purchase clause which kills a deal by UA
You must know a lot more than me and most of the other folks in this thread.
Called the MoM? Jeez, I had no idea! Fill me in on its concrete details (the ones UA needs to know right now) - its size, performance, range, price, and most importantly - delivery date.
How do you figure it fits within their time frame? UA is running out of options for NB / longer range routes when you start looking a few years out.
Your own comments contradict themselves. On one hand you say the MoM "fits into their timeline perfectly" which would be 6+ years AT BEST. Yet you go on to say that if UA was going to order the 321NEO/LR they would have done it already? Those are opposite lines of thinking - and personally I think it's a mix of the two right in the middle. UA needs something in the next couple years - gambling on something they can't even remotely quantify in the MoM is very risky.
They know what they're getting with the 321, they can get them fairly quickly, and it already shares fleet comonality with their maintenance and crew ops. It's also guaranteed to be cheaper than the MoM, and currently offers a ridiculous CASM advantage over the 757 somewhere over 20%.
