Audio Entertainment was risible...nearly non-existent. Searched and searched for CLASSICAL MUSIC and was sorely disappointed. Video entertainment wasn´t much better. The worst I´ve experienced in twenty or more airlines.

We were fortunate to be very early to get almost immediate assistance. If more ground staff were available to help with checking in the queues around us would have reduced more rapidly.
