Heathrow told to cut passenger charges.

It's not the airport's passenger fees that are the problem at Heathrow, it's the UK government departure duty that's the real problem there.

Everyone who has tried to use frequent flyer miles for LHR knows all too well about all the fees and charges.

Its amazing how those fees vary from airline to airline. I save about $600-800 round trip in fees switching from BA to AA.

Frank II- those are BA’s carrier fees. Totally different from airport fees or taxes.

I know those are carrier fees. But the difference between airlines is ridiculous.

Using AA miles, roundtrip from USA to London, AA's fees were $400. BA was $1200.

BA did announce in December they would let people pay less in fees and more in miles.

The British-based transatlantic carriers have a balancing act to do because of the differing policies in force in the UK and the USA. The American credit market looks crazy from here, with hundreds of thousands of "points" (to be generic) being given away as enticements to sign up on even fairly basic cards. They can afford to do this because of the weak consumer regulation in place on credit card interchange fees.

By contrast with the 0.2-0.3% fees in the British market cards introductory offers (and for that matter ongoing ones) can't be generous at all apart from ones aimed at high spenders. Although this is offset somewhat by direct promotions it means there are a lot more points sloshing around in the USA than the UK. Demand has been managed so there is some availability by charging fees, and these can be sometimes disproportionally high on singles/returns originating in the USA.
