Cheap flights from Belfast to Madrid

Madrid sits inland, so the pattern is plain: long, hot summers, mild springs and autumns, and winters cooler than much of Spain. Daylight swings with the season — evenings stretch out by June and draw in early again from November. Fares follow roughly the same curve, and the calendar's low point is March, once spring has begun but before the peak heat and the main holiday blocks.

The fare calendar here runs from October through to the following August. Book ahead of Christmas and the school-holiday weeks, when the cheaper seats go first, and start your hunt with midweek departures otherwise — the month-by-month view makes the March low easy to spot.

What the fare includes is where these airlines really differ. Easyjet and Jet2 price like the low-cost carriers they are: the base ticket usually buys the seat and a cabin bag, while hold luggage, seat selection and changes appear as extras. British Airways and KLM Royal Dutch Airlines lean full-service, with more of those costs built into the fare.

Nothing flies nonstop here, so BA CityFlyer, Aer Lingus and Emerald Airlines appear in connecting itineraries alongside the rest, and the same journey can be built low-cost, full-service or a mix. Check each result's terms: transfer time, baggage and what protection you have if the first flight slips.

If your connection brings you into Madrid in the evening, the ground transport question changes: the metro and the airport buses thin out overnight, so keep a taxi in reserve and confirm your accommodation can take you in at a late hour.

You'll land at Barajas, north-east of the centre — far enough out that you'll want a ride, but with the metro, airport buses and taxi ranks closing the gap quickly. The terminals are spread apart, so leave slack if Madrid is a stepping stone to somewhere else.

• Check what documents Spain asks of United Kingdom passport holders and keep yours valid past your return date.
