Overall I was very pleased with the high level of Air Serbia customer service from both ground staff and cabin crew. The short haul International Business Class seat is the same as Economy but limited to row 1 and curtained off at head level. Drinks & snacks were offered free of charge.
Sat in 1A and there was no one else in row 1 Middle seats (B&E) would be blocked off. Fortunately the excellent Air Serbia Business Class Lounge in Belgrade made up for the lack of comfort expected in the Business Class Cabin. Get to the lounge early to enjoy a delicious selection of food served up by the in house chef and be waited on by very attentive lounge staff.
