The big-screen Air. Same thin body, a lot more room.
15-inch Macbook Airs
Every listing below is a 15-inch Air. The M2 (2023) and M3 (2024) share the same 15.3-inch body, screen and speakers — so pick on price, colour, condition and battery. Fair is the best value with honest cosmetic marks; Excellent looks like new. All fully tested, with a 12-month warranty.
15.3” Liquid Retina · 10-core GPU · six-speaker sound · up to 18h video · 1.51kg · fanless & silent
If you work mostly at a desk, or you've ever squinted at two windows side by side, the 15-inch is the one to get. It's the same silent, fanless Air — just a lot more room to work, and the speakers are easily the best in any Air. Barely heavier than the 13-inch, and you notice the screen every single day.

Two generations on this shelf
15-inch M2 or M3 ?
Screen, speakers, ports, battery life, weight and colours are identical between the two. Honestly? Unless you need two external monitors, buy whichever is better value on the day.
Both are far quicker than the Macs people upgrade from
Geekbench 6 multi-core — rounded averages from Geekbench's public Mac charts. The two Intel machines are shown as reference points, not as alternatives. Higher is better.

Common Questions
Is the 15-inch Air worth it over the 13-inch?
If you work mainly at a desk, or you regularly have two windows open side by side, yes — the extra screen space is the kind of upgrade you notice every day, and the six-speaker sound system is a genuine step up. If you carry your laptop everywhere and value every gram, the 13-inch is the better travel companion. Both use the same chips and have the same battery life.
How heavy is it — can I still carry it every day?
Comfortably. The 15-inch Air is 1.51kg against 1.24kg for the 13-inch — about the weight of a paperback more — and it's still only 11.5mm thin. It's a laptop people carry to lectures and on trains every day; it just fills more of your bag.
15-inch M2 or M3 — which should I choose?
They share the same screen, speakers, ports, battery life, weight and colours. The M3 is roughly 20% faster and can drive a second external display with the lid closed; the M2 is usually better value. Unless you need that second monitor, buy whichever is the better price when you're looking.
Can it run external monitors?
Yes. Both take one external display up to 6K at 60Hz. The M3 can additionally run a second display when the lid is closed (with an external keyboard and mouse). If you want two monitors with the laptop screen still on, that needs an M4 — see the full Air range.
What's the difference between Fair, Good and Excellent?
Purely cosmetic — every Mac is fully tested and works perfectly regardless of grade. Fair has noticeable scratches or light dents (our best value), Good shows light signs of use, and Excellent looks like new. See our grading guide with photos.
What's included, and what about warranty and delivery?
Every Mac comes with a fully compatible charger, a 12-month RTB hardware warranty, 14-day returns, an 85%+ battery-health guarantee (under 400 charge cycles) and free insured next-day UK delivery on weekdays.
Discounted Air One-Offs
Single units in mixed cosmetic grades — fully tested, same 12-month warranty, priced to clear.
