First hand experience sitting in Level premium flying Barcelona to San Francisco.
Was very anxious but this is fantastic. Very clean, spacy.
Recline and legroom are great on par with any other airline.
We have flown premium and business with other major European airlines including Virging and Swiss and can confirm level premium is great.
You get welcome kit, headphones, blanket, pillows food everything. Alls included in premium so don’t need to worry about it.
Finally resting my anxiety to peace.
