Air India tops the list of passenger complaints lodged against Indian airlines in July this year, followed by no-frill carrier SpiceJet, official data shows.
Most air travellers, who have lodged complaints against the airlines, complained of problems relating to delayed flights and their customer services.
While Air India topped the list with the maximum of 213 complaints, it was followed by SpiceJet with 129 and IndiGo with 92. These carriers were followed by GoAir with 81 complaints and Jet Airways 61, the data for July showed.
The least number of complaints -- three and two -- were registered against new carriers AirAsia India and Air Costa respectively.
Officials said these complaints have led the DGCA to tighten the screw on airlines, especially on checking instances of rude or unhelpful behaviour of their staff at airports and in the aircraft.
The air carriers have also been told to improve quality of service particularly when the flights have been delayed or cancelled, they said, adding they have been asked to follow the laid-down guidelines about provision of snacks in case of delays and accommodation in case of last-minute cancellation.
However, they said that the number of complaints have to be seen in terms of the number of flights any airline, including Air India, operated on a daily basis.
They also pointed out that there was a tendency among some airline staffers not to register complaints, saying stern action could be taken against the staff or the airline whenever such instances came to notice.
Surprise checks being carried out by the regulator on a regular basis at times focused on these issues, they said.
The data, however, also showed that substantially less number of complaints were registered with the Directorate General of Civil Aviation (DGCA) in July compared to June. The number of complaints in July was 581, while it was 900 in 900 in June.
Almost 30 per cent of passenger complaints related to troubles with flight cancellations or delays, while about 25 per cent of passengers expressed discontentment over customer services of various airlines, the July data showed.
The percentage of complaints about staff behaviour in July was 11.5 per cent, compared to 7.9 per cent in June.
While lost baggage complaints totalled over 18 per cent in July, it was 23 per cent in the previous month.
On flight cancellations, they said the maximum cases related to technical trouble with aircraft, which stood at 39.2 per cent of the total cancellations.
However, the rate of cancellation in July has been only 0.79 per cent, compared to 0.87 in June, the data showed.
