I cannot understand this silly attitude!
Slot times are provided to expedite the flow of air traffic. If this can be improved upon by controllers and pilots being flexible, so much the better for all.
This vindictive attitude merely drives customers to use a different airport. Helicopters are not used by the masses, only the ones with more money and clout. If these people take their business elsewhere (many of them DO have a choice where they fly from), the airport shoot themselves and their operators in the foot.
BTW, what the HELL are EGLL doing with the "H" in the middle of the southern taxiways anyhow? This is not a safe way to operate, especially with regard to Cat A ops and the requirement for clear area departures.
It's time this airport and a couple of others got their act together with regard to facilities for helicopter operations.
