They’re using DHL/Do&Co trucks to help out. Yes it is very labour intensive. This is balanced out by not having many flights to cater and plenty of spare rampies.
Thanks champair79 for that information. Do you know if they use trolleys in the cabin to move the cargo ? Those seats, especially in Business and First are very expensive and there has to be incidental damage to them by the nature of loading/unloading, or are the rampies schooled in the art of gentle movement ? ;-)
