How Martin Lewis Says You Can Sit Together on a Flight Without Paying Extra

Booking a summer vacation already feels like a financial workout before you even leave your front door. On top of flights, accommodations, and everything else that comes with traveling, airlines have found yet another way to squeeze money from passengers through seat selection fees. Consumer finance expert Martin Lewis has been laying out exactly how families and solo travelers can sidestep these charges and still end up sitting where they want. With the summer travel season fast approaching, his advice could not be more timely.

According to Money Saving Expert, the average family of four can end up spending more than $315 just to pre-book their seats together on a round-trip flight. That is a meaningful chunk of money that most families would rather spend on actual experiences at their destination. Lewis explained in his newsletter that there are real ways to get around this cost entirely, and it largely starts with knowing which airline you fly with. Being strategic about that decision alone can save a family a surprising amount before the trip even begins.

For families, the top piece of advice from Money Saving Expert is straightforward — check in as early as the airline allows. Most major carriers, with the notable exception of Ryanair, say their seat allocation systems will actively try to keep passengers on the same booking seated together. People who have already paid to reserve their spots get priority, but if availability exists when you check in, there is a solid chance your group ends up together without an extra fee. It is not a guarantee, but for many families the strategy pays off nicely.

When it comes to traveling with children, the Civil Aviation Authority has guidelines stating that airlines should aim to seat parents close to their kids. If that cannot happen, youngsters should not be placed more than one aisle or seat row away from a guardian. The CAA also says parents should not have to pay extra fees to avoid being separated from their children on a flight. Money Saving Expert does note, however, that these are guidelines rather than enforceable rules, which is why airline choice still matters so much.

Knowing which carriers actively support families is the real game changer here. British Airways, TUI, and Virgin Atlantic all guarantee that children under 12 will be seated with at least one adult from their booking. British Airways also offers free seat selection for travelers with a child under two. American Airlines and Wizz Air extend their guarantee to children under 15. Air France, Jet2, KLM, and Norwegian all have systems designed to seat children under 12 alongside adults from their group, while EasyJet strongly encourages early check-in to give families the best possible shot at staying together.

Solo travelers, interestingly, are advised to do the exact opposite and wait until the last minute to check in. When other passengers choose not to pay for premium spots like extra-legroom seats, those seats sometimes get handed out for free to late arrivals during check-in. It is admittedly a bit of a gamble, but for someone flying alone without rigid expectations, it can turn into a genuinely great deal. Whether you are traveling solo or wrangling a family of four, understanding how check-in timing and airline policies work together is the smartest tool you have for keeping your travel costs down this summer.
