I am, in fact, alive. Just been really busy and I ended up getting a different phone so I’m not accessing here on my phone.

Fun fact: All of DEN’s flights to LHR (UA27, UA262, and BA218) depart in the next 2hrs. And DEN-CDG (AF631), departs in 10mins.
A couple of friends just boarded UA27 to go out to Paris (via London) to meet my other friend who’s been traveling around Europe for the past two weeks.

Oh no, it actually isn’t.
The standard MTOW for the A321neo is 97t, so we’ll go with that.
(Actually ignore the figures I provided earlier, they were for maximum continuous thrust instead of maximum takeoff thrust.)
The A321-251(NX) has a T/W ratio of approximately 0.301 while it is closer to 0.310 for the A321-271(NX).

What thrust did you use for each engine?
According to what Wikipedia, the PWs produce up to 147.28kN each. With a rough (but close enough) approximation that 1 ton = 10kN, that gives us a T/W ratio of 0.303. In contrast, the CFMs produce up to 143kN, giving us a T/W ratio of 0.294. Funnily, the A320-271N has a T/W ratio of 0.305 going by the same criteria.
However, remember, T/W ratio isn’t the only factor at play here. You might as well consider the wing load. Simply put, heavier aircraft with essentially the same wing = higher takeoff and landing speeds = significantly more runway needed. And I don’t think I need to say it isn’t exactly the wisest of ideas to try that on a relatively short runway right in the middle of the largest city in South America, especially after what happened in July 2007 (though seeing A321s blasting off from here would be super cool).

Yay, car guy is back.
The time I flew back from TLS, I found that the baggage was coming out really slowly, and it was a very long wait before I actually got my bag
Happy freedom day for all Americans I guess

Not really. The A321neo’s takeoff speeds aren’t too far off from that of the A320neo - the difference in takeoff distance between the two are within 100m (1951 vs 1988m) due to modified wing and flap design.
One advantage the A320neo family has over the 737MAX is a higher tail/ground clearance - allowing for a steeper rotation angle and lower takeoff/landing speeds.
Whoever did the conversions weren’t very good at it then. I used the figures in pounds for my previous calculations - and they seem to be quite a bit higher than those in kN/kg. We’ll have to dig deeper to actually find out which set of data is more accurate.
Still, the T/W ratio difference between the 251 and 271 (or rather 271 and 251) is about 0.01 - not a massive difference but still very possibly a noticeable one.
(For reference, the T/W ratios for the 787-9 and A330-900 are approximately 0.251 and 0.258 respectively, using metric figures.)

At least you’re not one of the weirdos that’s says “kiloMeTrE”.
Also, you’re in Phoenix right? Go look at the DC-10 tankers.
