Johannesburg - Distressed low cost airline, 1time, is expected to retrench 15% of its staff across the country as a result of financial losses, the SABC reports.This comes amid criticism by smaller airlines of the state's decision to give South African Airlines (SAA) a R5bn guarantee, which they say gives the national carrier an unfair advantage. One Time CEO, Blacky Komani, says retrenchments will be necessary as part of cost cutting measures."There is about a 30% cut in our fleet. The fixed course that goes with that has to be proportional to the number of aircraft that we are operating. Part of that involves us exiting routes that are not profitable and maintaining routes that are profitable for the airline," Komani said.
