Although I'm currently working from home, with no possibility of travel, let alone long haul travel, in the short/medium term, this news item struck me as interesting. If patents give an indication of future trends it seems that airlines are looking to how they can improve the customer experience - although I think I'd prefer they took some surveys and listened to the results rather than feeding me a sensor that will transmit results influencing when I'm offered a drink/have the lighting around me changed etc. In reality the majority of this patent application is directed to less invasive methods of monitoring, but still this is definitely an option that is considered!
Yet some British Airways passengers, in the future, may be given a snack with a difference: an ingestible sensor that transmits how you are feeling so that cabin crew are better able to provide what you need. BA is a busy company these days, as the airline seeks to compete with low-cost European rivals and the aviation-empire-building Gulf carriers. Three of the busiest people at the airline are Daniel Jobling, Estelle Levacher and Glenn Morgan. I don’t know them personally, but I do know that they are listed as the inventors on one of the most unusual airline patents I have ever read.
