Indian Airlines and Jet Airways on Friday revised the advance purchase fares in most of the sectors from next month.

However, the other major private carrier, Air Sahara, has no plans at the moment to take a decision on revising its Apex fares. "We have not looked into this as yet," its CEO U K Bose told PTI in New Delhi.

The percentage increase in the Apex fares of Indian Airlines and Jet Airways varies from sector to sector, though the hike ranged between 8 and 12 per cent.

Indian Airlines increased its Smart Apex fares for purchase before 7 days and 21 days, the public sector carrier said in a release.

The Indian Airlines said, "All tickets issued on or after December 1 for travel commencing on or after December 8 in case of D-7 Apex fares and December 22 in case of D-21 Apex fares will be at revised fares."

Announcing similar dates, the Jet Airways said its revised three-tier Apex fares would be effective in 59 sectors.

The Indian Airlines also announced the discontinuation of Apex D-7 scheme on Mumbai-Calicut sector (IC-596/598/595/597), Chennai-Mumbai sector (IC-571) and Cochin-Mumbai sector (IC-595/596 and 014) with effect from December 1.
