Cheap flights from Glasgow to Bilbao

The stretch from late spring through summer is when fares on this route climb, with school holidays and peak Spanish holiday season pushing prices up and seats filling earlier. Work back from March, the cheapest month on this route, if your dates are flexible — the quieter shoulder months around it also tend to sit below the summer peak. Fares are published from October through to August on this page, so you can compare the winter and spring months side by side on the price calendar before settling on a date.

What you feel first between the carriers is the fare structure rather than the aircraft. Easyjet, Jet2, Aer Lingus and the others all route you through a connection — none of them flies this pair nonstop — but the budget carriers typically sell a basic seat and charge separately for checked bags, while the legacy names such as KLM Royal Dutch Airlines, British Airways and Eurowings Discover bundle more into the ticket price. Emerald Airlines and Aer Lingus funnel you through Dublin, KLM through Amsterdam, so the airline you pick usually decides where you change planes. Compare the total with bags added, not the headline fare alone.

If your connection runs late, you may land at Bilbao airport in the evening, when the queue for buses and taxis is thinner but shops and car hire desks are already closing. The airport sits outside the city, reached from the centre by a regular bus link, with taxis taking the road route down into town. Bilbao is the only airport in the facts for this destination, so there is no second airport to worry about — just check whether your arrival time leaves you a sensible bus or a pricier taxi ride.

Country facts: Wikidata

• Check Spain's current entry rules and that your passport meets them before you book anything.
• Confirm which carrier operates each leg, since separate tickets can leave you unprotected if the first flight is delayed.
• Check whether checked baggage is included in the fare or costs extra with the low-cost carriers on this route.
• Compare connection times, because a short layover in Amsterdam or Dublin can turn into a missed second leg.
• Check April to June and September-adjacent dates against the summer months on the calendar before locking in a date.
