Tigerair said that its introduction of new capacity and destinations over the past year has enabled it to consolidate its position as Singapore's largest low-cost carrier (LCC). Based on the recently published second-quarter results of the Customer Satisfaction Index of Singapore, conducted by the Institute of Service Excellence at SMU, the service standard of the budget airlines sub-sector improved by 4.9 points to 67.5 points. This closes the gap on full-service airlines, which improved 2.5 points to 77.1 points.
