Summer brings the longest days and the biggest crowds. Airports are at their busiest, so arrive early, check in online and keep your carry-on simple to move through security faster. Thunderstorms in the afternoon can delay flights in North America and parts of Asia, so an earlier departure can be more reliable. Heat also matters: in very hot places like the Gulf, Southern Europe and parts of the US, plan outdoor sightseeing for early morning and evening. Families should book seats together early.
Flying in summer
When: June to August in the northern hemisphere. In the southern hemisphere (Australia, New Zealand, South Africa, much of South America) the seasons are reversed.
Peak season for family trips and Europe. Book earlier and be flexible on days of the week.
Making the most of the season
- Look for shoulder weeks at the start or end of the season, when the weather is still good and demand is lower.
- Check local holidays at your destination as well as at home; both affect prices.
- Mid-week departures are often easier on the budget than weekends.
- Pack for the weather and check the baggage rules for heavier clothing.
How to compare fares fairly
The first price you see is rarely the whole story. Before you choose, add the extras you actually need, such as a checked bag, a seat together if you are travelling as a family, and any change or cancellation flexibility. A fare that looks lower can end up costing more once those are added, while a slightly higher fare that includes a bag may be the better deal. Compare the total for your whole party, and check the connection time and airport on every itinerary, not just the price.
Flexibility is the most reliable money-saver. If your dates can move by a day or two, use the calendar view in the search results to see how prices change across the week. Flying midweek or at less popular times of day often helps. Setting a price alert and booking once a fare falls inside your budget is calmer, and usually smarter, than checking every few hours.
Before you book: documents and rules
Check that your passport is valid for the whole trip (many countries ask for six months beyond your return date), and look up visa or electronic travel authorisation rules on the official government website of every country you will enter, including any you only connect through. Baggage allowances differ by airline and fare type, so read our baggage rules guide and pack using our travel checklist.
