'Inconsistency' in air passenger duty refunds

[mhm]

Parents due partial refunds on their children's air tickets face a variety of ways to claim the money.

Air passenger duty (APD) for children under the age of 12 on economy travel will be abolished from 1 May.

That means some passengers who have already booked and paid for flights that take off after 1 May are due a refund of the duty.

Some airlines are giving refunds automatically, but others require passengers to fill in a claim form.
