Airport operator MAp Airports Ltd, Sydney Airport's majority owner, has reported on Friday that 31 percent spikes on its first quarter earnings with $100.71 million amassed in three months leading to end of March, as compared to posted income the same period last year.

In a report by AAP, the Sydney-based company said that proportionate earnings per stapled security of 5.4 cents jumped by 20 percent from 4.5 cents last year.

MAp Airports was borne out of the Macquarie Group and became a different entity in October last year following compensation of $345 million as one-off termination fee to the satellite fund.

The airport operator currently maintains 74 percent ownership of Sydney Airport and also holds 30.8 percent interests in Copenhagen and 36 percent stakes in Brussels Airport, with more interests in a number of Mexican airports.

MAp chief executive Kerrie Mather said that the company's airports started strong in 2010 as she stressed that "MAp's portfolio delivered a solid performance in the first quarter, driven by the rebound in passenger numbers, higher load factors and increased airline capacity."

She said that air traffic has been firmly re-established in all of MAp's major airports and they are returning earnings that are beyond expectations, as she cited that traffic across MAp's airports shoot up by 7.6 per cent in the first quarter as revenue jumped by 8.7 per cent.

The company attributed their promising performance to a significant ascend in both leisure and business travels at Sydney Airport in the three months leading to March.

MAp pointed to Sydney Airport's retail revenue which went up by 10 percent to $51.4 million in March as the company noted that newly opened retail and duty free stores at the terminal partially contributed to the quarter sales figures.
