I'm sorry if this topic has already been discussed but, which engine is better for the A319, A320, A321 as far as reliablility, fuel efficiency, etc? Also, which engines do most customers choose for that family of airliner? How is the new PW engine for the A318?

Wouldn't the lighter engine be the better choice.... thrust output being equal? Because, one options out weights the other by roughly two thousand pounds.
I'm not well versed on the specifics of fuel burn rate, but perhaps, someone with a little more technical knowledge could enlighten us... Because, I'm sure that would be another key consideration.

LOL...well....UA has the IAE engines. Yesterday on takeoff to TPA from ORD, one of our A320's had #2 engine explode. It came back on fire. Every last turbine blade in the back end of that thing was busted and/or melted. I saw it after the fire Dept. got done w/ it.

CFM is better for reliability and cost of repairs / parts etc. It is also lighter, allowing for more useful load. The newer -5B versions have better power than the -5A and are flat rated to a higher temperature. Nice for high and/or hot ops.
IAE is better for fuel economy, but the -A1 version with thrust bump is just stupid! The -A5 has better power and flat rating as well, but is a real heavy beast.
