This question is a bit like asking why car designers don't replace V8 engines with a pair of daisy-chained 4 cylinder engines. Whatever two separate engines connected inline can do, will almost ...

Why don't airliners use engines one behind another?

Most airliners already have 2 engines, and can operate on one just fine. Your suggestion would be very costly, adding massive weight and complexity, and burning way more fuel for additional engines ...

What does the suffix "A“ mean on specific PW1100G(A) engines?

It probably refers to "Advantage" series, PW1100G-JM Advantage. About 1% more thrust and uses a little less fuel. Certified in 2023 and entered service in 2024. https://prd-sc102-cdn.rtx.com/...
