Pakistan International Airlines (PIA) is seeking to lease up to five new narrowbody aircraft.
The carrier has issued a tender calling for interested parties to bid for the lease of up to five aircraft of 140 or more seats, but has not specified an aircraft type.
According to the terms of the tender, the aircraft will be leased on a 8-10 year financial lease term to cover the aircraft and induction costs, with deliveries to be made up to 2014.
Conditions for the tender also include stipulations that the aircraft be delivered in brand new condition and PIA having the right to sub-lease the aircraft to other parties.
Proposals are due on 9 July.
Flightglobal's Ascend Online Fleets database shows that PIA's narrowbody aircraft fleet consists of three Boeing 737-300s.
In early May, the carrier issued two tenders seeking to lease up to 12 narrowbody aircraft on three and six-year terms. Those tenders came after an earlier deal with BOC Aviation to lease five Airbus A320s collapsed after the carrier could not meet its financial commitments on time.
PIA says it is still evaluating the responses to those tenders and it still intends to take delivery of those aircraft in addition to the five new aircraft sought in the latest call for proposals.
