I posted this in Philippines forum yesterday but thought it may be of some interest in TA's air travel forum.
I have never experienced this anywhere else in the world but know from the occasional media report that similar things do occur.
On Sunday along with 93 other passengers I boarded the 0910 Manila NAIA,Philippines (Terninal 4 'Old Domestic') SEAir flight to Tacloban at 0840. Everyone was aboard the Airbus A319 so we departed 20 minutes early at 0850.
However I noticed after 12 or so minutes that we seemed to be circling back on the taxiways to the terminal. A man got up and walked off: I thought that he'd somehow boarded the wrong flight (which would be a security breach, especially since a security guard or airport worker checked our boarding passes on the tarmac as we boarded by either front or rear stairs.
However I was wrong. Apparently one of the two hostesses (the other two were male) had asked the male passenger to turn off his IPod or iPad (I don't know which) more than once and he had declined. As a result he was kicked off, but left without protest. A policeman soon appeared and took the staff member's details.
We spent 15 ninutes or so back at the gate, stayed on the plane.; it departed about 20 minutes late but due to a fast taxiing and slack schedule only arrived Tacloban at 1030, five minutes late.
This is the first time that I've ever left a terminal with a different number of passengers to those who arrived on a flight at a destination.
I gather that there is some debate about whether such devices actually interfere with air navigation equipment.
It would be costly for SEAir, 40 per cent owned by Tiger Airways of Singapore but effectively now controlled by the latter and which started domestic airlines to use up extra fuel during the half hour or so delay.
