Not just about the Light fare class, but this seemed the most appropriate place.
On the
LX baggage info page, a "Personal Item" is defined as 40 x 30 x 10cm; no weight limit specified.
However, OLCI explicitly states that the personal ite can be 55 x 40 x 23cm, i.e. the same size as a carry on suitcase, with a weight limit of 8kg.
What is correct?
