British Airways has said that its customers face being made to rebook if they are found in possession of an uncharged device.
So if the device has to be charged, then that means you dare not use your Kindle, phone, or whatever while delayed awaiting departure in case the battery runs down too far.
I retired more than 15 years ago after 40 years as a pilot. I have flown just twice in those past 15 years. I simply can't be bothered with all the hassle.
I wonder how many others don't fly nowadays, not out of fear, but because it is so damn tedious?
