Air Passenger Duty reforms are among the tax changes coming into force today, which will mean cheaper long-haul flights.
The changes, announced in last year’s Budget, will see the two highest rates – bands C and D – abolished.
Band C affects people travelling over 4,000 miles and Band D affects people travelling over 6,000 miles
The Treasury said this will eliminate the highest rates for travellers visiting destinations such as China, India, Brazil and "many other emerging markets" including the south Asia region.
A business class Band D flight (includes Australasia, Malaysia and Indonesia) previously attracted an APD levy of £194 but this will drop to the Band B rate of £138.
However, passengers in band B (2,000 to 4,000 miles) will see APD rise from £69 to £71.
Further reform will happen on 1 May, when children under 12 will no longer have to pay APD. Those under 16 will be exempt from March 2016.
Passengers on direct long-haul flights whose journey begins in Northern Ireland are exempt from APD.
A spokesperson for ABTA said while the news is welcomed British travellers still face the “highest air taxes on travel anywhere in Europe”.
In January, the government confirmed the decision to devolve power to charge APD to the Scottish Parliament.
Scotland is now expected to reform and eventually abolish APD, following a commitment made last year by the Scottish National Party.
