No, I don't want to read your duty-free magazine, I've got Harry Potter on my iPhone.
A report from IMS Research suggests the appeal of in-flight movies is waning, with 50 per cent of American electronics users operating their devices while travelling on planes.
Of that group, usage accounts for 40 per cent of flight time on journeys that last at least an hour, though eight per cent admit to spending a whopping 80 per cent on at least one of their devices.
Some airlines have started to offer wi-fi on flights, though it's said to make little difference to the amount of media that users are gobbling on their phones, tablets etc. However, 30 per cent of respondents abstained from using personal electronic gizmos at all.
Rose Yin, market analyst at IMS Research, said: "Although not all passengers use inflight wi-fi, it is clear that many still brought along and made use of their electronic devices to help pass time onboard.
"We also found that regardless of whether inflight wi-fi is offered or not, the amount of time spent on these devices varies little; as passengers can just prepare enough offline content prior to boarding to help entertainment themselves later on."
