A bench of justices D K Jain and Madan B Lokur asked the Tribunal to expeditiously decide on the validity of the fee which has been challenged by an NGO, Consumer Online Foundation.
The NGO challenged the levying of ADF of Rs 200 and Rs 1,300 per embarking domestic and international passengers at New Delhi's Indira Gandhi International (IGI) Airport for 18 months from December 1, 2011 to May 2013.
In the earlier hearing, the bench had observed that ADF collected from passengers was a "little unreasonable" and suggested that VIPs be charged like in abroad for use of special lounges instead of burdening common travellers.
"You are a little unreasonable to passengers. In many airports (abroad), such a huge amount of fee is charged for VIP rooms. In London, they charge 400 pounds per passenger for a small room in VIP lounge, why can't you reciprocate here"? the court had said.
