High Utilisation & Capacity Modulation at SpiceJet

Wet Leased SpiceJet 737 OK-TVX OK-TSF

Besides all the visible innovations that SpiceJet is grabbing the headlines for, the airline is doing certain other things quite differently.

Any airline will like to make the most of a peak season by increasing flights, and providing increased connectivity and flight options. There are two ways to do this : by growing the fleet or by flying the airplanes harder. SpiceJet is doing both.

The airline does not yet seem to be ready to lease more airplanes the conventional way. It instead is wet leasing airplanes from eastern European airlines, which have capacity to spare. In the month of October, the airline will be inducting 6 Boeing 737s on a wet lease (ACMI lease) basis – which means the airline will not have to bother about flight crew, cabin crew, maintenance and insurance. Wet leases can turn out to be more expensive than a dry lease with in house crew, maintenance and insurance, but it offers SpiceJet one big advantage – to modulate its capacity to suit seasonal demand.

SpiceJet today is the only airline in India to be actively wet-leasing airplanes to bridge capacity shortfalls.

The airline presently has one Airbus A319 wet leased, and 2 of the 6 wet leased Boeing 737 NGs to be inducted this month have arrived – OK-TVX and OK-TSF. OK-TVX flew for SpiceJet during the summer peak season, along with two other Boeing 737-800s. The two 737s arrived on 8th October, 2015.

The airline’s remaining Boeing fleet is all dry leased, and the Q400s are owned. Of the 20 Boeing 737s, 16 are Boeing 737-800s and 4 are Boeing 737-900s. Before the 2 wet leased airplanes arrived, one Boeing 737-900 was undergoing heavy scheduled maintenance, ‘C’ checks. After the two leased airplanes arrived, a Boeing 737-800 went into scheduled maintenance. In total, the active narrow body mainline jet fleet as of today is comprised of 15 dry-leased Boeing 737-800s, 3 dry-leased Boeing 737-900s, 2 wet leased Boeing 737-800s and 1 wet leased Airbus A319, in addition to 14 Bombardier Q400 turboprops of which 13 are active. The total active fleet is 34 airplanes strong, which is expected to rise to around 40 during November-December. The peak season starts in a week’s time.

To aggressively take on the domestic and international markets despite a small fleet of airplanes, SpiceJet has been pushing its Boeing 737s to fly much harder than usual. Some of the Boeing 737s operate 19:30hrs, 17:50 and 16:35 hrs. These patterns flown by the 737s witness the airplanes flying hard during the day, and operate long international sectors at night/early morning.

Of the LCCs in India, only two fly international – SpiceJet and IndiGo. IndiGo, which also operates late night / early morning international flights, operates its airplanes only upto 17:45hrs of utilisation, on a pattern that involves a late night Chennai-Singapore return flight. One of the airline’s patterns is all-international with just 4 flights, MAA-DXB-TRV-DXB-MAA, which uses the airplane for 17:35hrs. Both these patterns, however, are not as heavy in utilisation as SpiceJet’s.

While SpiceJet pushing its airplanes to fly harder increases revenue potential and dilutes costs, it also results in a higher chance of cascading network delays in case one flight gets significantly delayed. Having significant gaps between patterns reduces the chances of the delays of one day from cascading into the second day.

On the Q400 front, the airline pushes certain Q400s to operate upto 13:15hrs per day, with an average, network-wide utilisation of around 11:30hrs. This is good for a turboprop that operates mostly domestic. SpiceJet’s Q400 turboprops are the only turboprops in India that fly scheduled international services.

    spicejet had closed its indore station..about 6-8 months back when rationalizing its network. poor hindsight in doing so. indore is one the most promising Tier III cities. Indigo way back in 2009/10 taken a chance ahd introduced a direct flight between indore to raipur(both big commercial cities), and it has paid off beautifully. indigo is the only direct operator between the two cities. another route, spicejet had chanced upon when getting the Q400’s was hyd to indore(another brilliant route, with gud yields, the indigo again is the only direct operator and the fares on the route have actually gone up since spicejet stopped operations).
