A PR blurb about new sleep pods installed at Dulles:

It's possible that Heathrow itself could do this, but given the number of hotels in and around the airport with some attached (as compared with Dulles where the hotels, other than the Marriott, are somewhat remote), I don't know that the airport authority wants to be perceived as competition for the hotels. On the other hand, I don't see that as a factor for BA.
Understanding that such an idea would likely be years away (even with half of the pods installed at Dulles, BA would have to clear 600 sf somewhere and that won't happen within the next couple of years), would this idea make sense for one of the Galleries Club lounges? The concept seems the sleeping equivalent of the current shower situation--small but useful spaces that could alleviate the temptation of some to spread their belongings over a sofa with the intent of catching a brief nap during a long layover. Although a little complex of these would take some space, they still look as if three or four of them could be squished into the space of one of the cabanas in the Concorde Room. And maybe this would be the kind of on-the-ground amenity that would go nicely with the improved onboard Club product.
