Flew BCN–JFK with Level earlier this year and honestly, it delivered what it promised: a clean seat, a safe flight, and a cheap fare. That said, if you’re not used to long-haul low-cost, the à la carte model can catch you off guard. No food, no free bag, no seatback screen . It’s BYO everything. I sprung for Premium on the way back and the extra space was totally worth it.
Would fly them again, but only if I’m packing light and expectations are properly set.
