As the plane has an automatic lifejacket for each seat it seems illogical to restrict the passengers from carrying their own .
Depends on the airline and the captain. Its about as illogical as charging the same fare for a slim person and an absolute bloater whilst doing excess baggage according to weight - but who ever said life should be logical. If that was what was intended, God would never have invented women.
