IndiGo, India’s largest airline by domestic market share, today accepted its first Airbus A320neo at Toulouse, France. The aircraft, serial number (MSN) 6799, and registered VT-ITC will be the world’s first Airbus A320neo to enter service outside Germany. IndiGo is the second airline to accept the A320neo after Lufthansa.

The A320-271N is powered by two Pratt & Whitney PW1127G-JM engines. Technical issues with the engines had delayed the delivery of these aircraft. At this stage, it is not clear if either the issues have been fully resolved, or IndiGo has benefitted from some sort of compensation from either Airbus or the engine maker Pratt & Whitey. The aircraft is expected to commence commercial operations on on before 15th March 2016.

The first flight for MSN 6799 was on 15th December 2015, nearly 3 months ago. The aircraft is fitted with 186 seats, six more (one row) than the other 101 A320s in the fleet, today. VT-ITC have 31 rows in the cabin, with no windows on the 31st row.

The geared turbofan (GTF) engines fitted on the A320-271N are expected to be quieter than the IAE V2527-A5 engines that power the current fleet of 101 aircraft. The engines are also expected to be more fuel efficient, delivering over 11% fuel burn advantage over the current engines.

The current engines (with the external casing) has a horizontal diameter of 2 meters. The neo engines, with the casing, have a horizontal diameter of 2.67 meters.

It is learnt that technical crew trained on the A320neo are for now based only at Delhi, Kolkata and Bengaluru. The aircraft will be based at Delhi, and initial routes may include DEL-CCU vv and DEL-BLR vv.

IndiGo was supposed to have been the second airline to receive the Airbus A320 neo. Despite the delay, IndiGo will still be the first Indian airline to receive the A320 neos, followed by Go Air. Deliveries to IndiGo are likely to happen in the summer of this year. Lufthansa, the first customer of the variant, is already operating the neo albeit short routes within Germany, between Frankfurt, Hamburg, Munich and Berlin.

Seat maps published by Lufthansa allow one to compare the A320’s cabin with the A320 neo’s cabin. Both cabins are of identical length, but have a key difference in the layout: The aft two lavatories are moved to the rear bulkhead, reducing galley space, and making space for one extra row of seats (see the image on top). Lufthansa’s A320ceos has 168 seats in its cabin (across 2 classes), while the A320 neo with the rearranged ‘SpaceFlex’ cabin fits 180 seats (across 2 classes), as shown below.

In the case of IndiGo and GoAir’s A320 neos, the cabin will be fitted with 186 seats (single class), 6 more than the present 180 seats fit in the cabin. Moving the lavatories towards the rear bulkhead, and eating into the galley space makes sense for low cost carriers, as the quantum of uplifted food is lesser than full service carriers. But the last row will be where the lavatories were earlier located.

The issue is not about sitting where the lavatories once were, but that the last row (which will be identified as row 31 on IndiGo and GoAir, and row 32 on all other airlines that skip the number ’13’ when identifying rows) will have no window, and little to no recline. This will, undoubtedly, become the least preferred row on the entire aircraft. To make things a bit more uncomfortable, the walls start moving inwards at that row, part of the taper of the aft fuselage.

Seat pitch on the 186 seat A320s will remain unaffected at 28/29 inches. But remember to keep an eye out for windowless row 31 and above.
