What to look for in a travel cot for flying
Weight is the single biggest factor. Most airlines let you check a travel cot free as baby equipment, but if you're flying budget carriers or transferring airports, anything over 7kg becomes a problem.
Pack size matters almost as much. Look for cots that fold down to airline carry-on dimensions (roughly 55 × 40 × 20cm) — these can go in the overhead locker on most long-haul carriers and save you a gate-check.
Mattress firmness is non-negotiable. The Lullaby Trust advises against thick soft mattresses for travel cots. A firm, flat sleep surface is safer even if less comfortable-looking.

The BabyBjörn Travel Cot Light is the gold standard for UK parents who fly often — 6kg, sets up in 15 seconds, and the included mattress is firm enough to meet safe sleep guidance.
For tight budgets, the Hauck Dream N Play comes in at around £60 and weighs 7.3kg. Not as quick to pack but perfectly airline-friendly for occasional travel.
The Nuna Sena Aire is heavier at 10kg but the side-panel mesh and zip-down access make it the best for older babies who climb.

Most UK airlines (BA, Virgin, Jet2, TUI) allow one travel cot per child free of charge as checked baggage — but you must declare it at booking or check-in. easyJet and Ryanair charge £25–£45 each way unless it's specifically listed in their baby equipment allowance, so check before you book.
If your cot fits carry-on dimensions, carrying it onboard is often less hassle than trusting baggage handlers. The BabyBjörn Light and Phil & Teds Traveller both fit most overhead lockers.
Safe sleep away from home
Travel cots work best when your baby already associates sleep with a consistent environment. Pack their own sleeping bag and a familiar muslin — the smell alone helps them settle in an unfamiliar room.
Avoid adding extra padding, bumpers, or positioners to the cot even if the provided mattress feels thin. The NHS and Lullaby Trust both warn against soft items in the sleep space.
Hotel-provided travel cots are a coin flip — many are old, stained, or missing the original mattress. If in doubt, bring your own.
