The impact of Air Passenger Duty is to be investigated by the Northern Ireland Affairs Committee.
A short inquiry will look at how Air Passenger Duty (APD) affects individuals, airports and airlines, businesses and tourism in Northern Ireland.
The inquiry will also look to contrast the UK rate of APD to the low rate in force in the Republic of Ireland.
The Committee will hold its first public evidence session on the inquiry at Parliament Buildings, Stormont on June 21.
A review of APD is currently out for consultation by the Treasury.
The Consumer Council says the tax should be scrapped because of Northern Ireland's dependence on flight connections to Britain.
Antoinette McKeown, Chief Executive of the Consumer Council said: "We are pleased the Northern Ireland Affairs Committee is focusing on a key issue for Northern Ireland consumers.
"The Consumer Council has been clear in demonstrating the impact APD is having on NI passengers.
"Northern Ireland's geographic location means consumers are more reliant on air travel compared to their counterparts in Great Britain.
"Increasing rates of APD for Northern Ireland airports could put at risk the connectivity and routes available from NI airports.
Ms McKeown concluded saying: "It is reassuring to see the Northern Ireland Affairs Committee recognising the need to investigate the issue of APD further."
