When flying from Redmond to Lisbon, the time of day you fly usually plays a role in the price. Save by searching for a flight in the evening, which can drop the price by up to 27% versus a flight in the afternoon.
Flying to your destination on a Tuesday can be more expensive, but this shouldn’t discourage you from finding affordable options to get to Lisbon. Check prices with Cheapflights to find a great deal for your trip.
