As stated earlier, there are errors to this report.
The A321NEO that PAL receives in February is not the LR variant. While the A321neo ACF story is correct, it does not have the range to fly 4,000nm.
According to
Airbus statement yesterday, The A321neo ACF is the base for a longer range (LR) variant known as the A321LR.
The very first of this type was just shown yesterday. The 3500nm-ranged CFM powered plane if you figure the livery. It will undergo ground tests prior to its scheduled first flight "in the coming weeks" according to Airbus.
Next to this might very well be the first PAL plane (cn8090) with P&W engines.The first delivery of A321LR is targeted for the fourth quarter of 2018. Air Astana is known to be the first operator of this LR variant.
Having said the facts, it can be told now that the six A321N frames PAL ordered were merely the Airbus Cabin Flex (ACF) frames with two auxiliary fuel tanks (ACT) and not the LR variant with 3 ACT for 4,000nm range.
This 97 tonnes base plane with almost 30 tonnes of fuel does have the range to fly 3,500nm at maximum payload according to PAL sources. With 168 passengers it can fly MEL with ease at 15-18t payload. Indeed they don't need the LR kind.
With six of them coming this year, we should see SYD on 2x daily and MEL daily flights in addition to inaugural March flights in BNE. We could see DEL in alternating days when they are flown.
The relieve A330's out of Oz is expected to fly MNL-AKL replacing the A340.
