The renovation will go on until May 2019. The food and beverage selection will be limited during the improvements. Breakfast will include for example bread rolls, yogurt and coffee, and after breakfast you can enjoy wraps, soup, salads and bread.
The shower cabins and sauna at the non-Schengen lounge will be closed as of 1 October 2018. If you are transferring and your next flight will be leaving from the Schengen area, you can use Finnair's Schengen lounge services. The renovations will not affect the opening hours, and you can enjoy the lounge services daily from 5.30 a.m. to 12 midnight.
