Before Séan Harrington flies for business, he always enjoys a quick spa. And when he touches down, he goes for a run and has another spa, this time with a massage. That way he is ready to face whatever the business day has to throw at him. Pampering, he says, takes a great deal of the stress out of business travel.

You might expect this of Mr Harrington. After all, he runs Elemis, a British spa and skincare company, which has joined with British Airways to equip its executive lounges with spas at Heathrow and New York's JFK. But he is not the only one who fits in a little spa R&R in at the airport.
