Sources said the Dubai side moved a proposal for the Indian carriers to shift to another airport terminal, which was opposed by the Indian team.
While there were indications that the two sides were coming close to an understanding on enhancing the bilateral seat entitlements by another 10,000-12,000 per week, there was no official confirmation till late tonight as the meeting, which had started at 1100 hours, was underway even at 2030 hours with no end in sight.
In 2012, Dubai had sought an increase by 20,000 seats per week in late 2012. However, at that time Indian carriers were not fully utilising their entitlements and so, no decision was taken on the issue.
Since then, Indian carriers, including IndiGo and SpiceJet, have started new flights to Dubai and utilising over 80 per cent of the entitlements. By summer schedule starting this month end, this number may go up to 95 per cent. This has prompted the government to consider Dubai's request now.
Officials had later said that these concerns would be kept in mind when they restart negotiations with the aviation team from Dubai.
