Virgin Atlantic has developed a coaching session to improve its crew's speaking tones while on duty, but the special skill will only be applied when addressing the highest-paying passengers of the airline.

The course will teach the crew how to whisper in an appropriate way, especially during night time, and get the right 'tone, volume and sentiment' when addressing passengers of the Upper Class. To be very specific, flight attendants will be trained to use a volume ranging between 20 and 30 decibels. This has apparently a soothing effect while taking care not to bother others. This specific volume will also make sure the night remains as peaceful as possible, allowing passengers to wake up all refreshed.

This voice training is part of a set of trainings; themselves part of the launch of the new and extremely fancy Upper Class Dream Suite which will open to the public in April. The different training courses include classes on how to 'read' passengers, how to wake them up in a suitable manner and how to be 'tactile'.

Upper Class passengers being those who pay the most for their flights - about 6,000 pounds for a return flight between London and New York for example - it is only logical that they get the best treatment possible. The whisper training has been carefully elaborated by several speech experts and already been experimented with on focus groups and test-flights to make sure it does the trick.

Besides the magical whisper, the Upper Class Dream Suite will have comfortable beds, freshly-designed seats, glassware and other fancy aspects to turn it into la crème de la crème of luxury travel. Richard Fitzgerald, the customer service training supervisor and the appointed whispering coach for Virgin Atlantic Upper Class, says that 'the new Upper Class Dream Suite is the ultimate in luxury and comfort and it's touches like these that make our in-flight service second to none.'

Perhaps it is worth paying a few thousand pounds more to get a nice whisper on your flight, but make sure you get your ears cleaned beforehand to avoid having your flight attendant repeating your order a thousand times, waking up everyone and turning the Dream Suite into a fiasco scene.
