Family Holiday Packing Guide: How Many Suitcases Do You Actually Need?
Every family has had the conversation at some point — are we bringing one big case or lots of smaller ones? Do the kids get their own bags? Does Grandma's suitcase count? Family holiday packing doesn't have to be complicated. The right luggage set puts the answer right in front of you: one set for your family, every size covered, nothing to figure out.
Whether you're jetting off to Majorca, heading to the Costa del Sol, or planning something more adventurous, this guide helps you pick the right set for your family — and explains exactly why a matching luggage set is the smartest packing decision any family can make.
The Simple Answer: One Set Per Holiday
The most common family packing mistake is building a luggage situation out of mismatched bags accumulated over years — a soft shell from 2019 here, a hard case borrowed from a parent there, two carry-ons that don't quite match and a holdall wedged in somewhere. It works, but it's messier than it needs to be.
A matching luggage set solves the problem in one purchase. You get every size your family needs — cabin, medium, large, and (in the 4-piece) extra large — all built the same way, all rolling the same way, all locking the same way. On the baggage carousel, you'll spot your bags instantly. In the attic, they nest inside each other and take up the space of a single case.
The only real question is: three pieces or four?
Which Set Is Right for Your Family?
Couples & Duos
3-Piece SetThe cabin case for essentials, the 28" large for one partner, the 24" medium for the other. Or use all three between you and bring home twice as much shopping. The 3-piece covers every couple's trip perfectly.
Families of 3
3-Piece SetTwo adults each take a case, the little one's clothes and toys fit neatly alongside — or give the child the medium as their very own bag. The cabin travels with whoever needs the most on-flight access.
Families of 4
4-Piece SetThis is where the 4-piece earns its place. Two parents, two children, and enough space for everyone's summer wardrobe, the beach kit, the factor 50, and all the gifts coming home. The 32" extra large is the family holiday game-changer.
Larger Families & Extended Holidays
4-Piece SetBigger families, longer trips, or anyone who wants the freedom to pack fully and not compromise — the 4-piece is the answer. 144 litres in the extra large alone handles everything you thought you'd have to leave behind.
What's in Each Set
Both Aerolite sets use the same quality throughout — ABS hard shell on every case, 4 dual 360° spinner wheels, built-in TSA locks, and smart organised interiors. The difference is simply the number of cases and the addition of the 32" extra large in the 4-piece.

Five Reasons Families Love a Matching Set
Spot yours instantly at baggage reclaim
Four matching green or charcoal cases coming round the carousel together are hard to miss. No more hovering uncertainly over someone else's large black case wondering if it's yours.
Every size sorted before you even start packing
The cabin, the medium, the large — and in the 4-piece, the extra large — are all right there. You don't have to wonder if you have the right bags. You have every size your family could need.
Compact nested storage at home
Not travelling? The entire 3-piece set stores in the footprint of the large case. The 4-piece nests into the extra large. One space in the wardrobe or attic handles the lot.
Same quality on every single case
The wheels roll the same on the 21" as on the 28". The TSA lock works the same on the medium as on the extra large. Consistent construction means no weak link in the family luggage lineup.
How to Split the Packing Between Cases
There's no single right answer here, and different families do it differently. But these three setups work well for the most common UK family holiday sizes.
| Case | What Works Well Inside | Who Manages It |
|---|---|---|
|
21" Cabin 38.8–44.6L |
Passports, boarding passes, snacks, kids' entertainment, change of clothes for the plane, medications, chargers and devices | Always in the cabin with you |
|
24" Medium 67L |
Children's full wardrobe, shared toiletries, sunscreen, travel adaptors, small beach items | Checked — shared family essentials |
|
28" Large 100.8L |
Full adult wardrobe for 7–14 days, shoes, swim kit, bulkier clothing | Checked — one per adult |
|
32" Extra Large 144.1L · 4-piece only |
Extra bulky items, coats and layers for cooler destinations, gifts, holiday purchases, sports equipment | 4-piece set · Checked · Return journey bonus space |
The Cabin Case: Your Family's Most Useful Bag
The 21" cabin suitcase that comes with both sets deserves a special mention, because it's the piece that works hardest on every single trip.
At 55x40x20cm it fits Ryanair Priority overhead lockers — the strictest cabin size limit of any major UK budget airline. Expand it to 55x40x23cm and it also fits Wizz Air, Lufthansa, TUI, British Airways, and Jet2. It holds 38.8 litres unexpanded and 44.6 litres expanded. That's enough for a full weekend away, or for all the in-flight essentials a family of four needs to keep the journey comfortable.
And crucially — it never goes in the hold. Whatever happens to the checked bags, the cabin case is always with you. That's where the passports live. That's where the kids' entertainment lives. That's where the medication, the charging cables, and the snacks live. Pack it intentionally, and it takes a lot of the stress out of the journey.

Frequently Asked Questions
Common questions about family holiday luggage sets.
How many suitcases does a family need for a holiday?
For most UK families, a 3-piece set covers couples and families of up to 3, while a 4-piece set is the better choice for families of 4 or more. The 3-piece (21", 24", 28") gives you cabin, medium, and large — covering everything from a weekend break to a fortnight abroad. The 4-piece adds a 32" extra large at 144.1 litres, which is the game-changer for bigger families and longer trips.
What is the best luggage set for a family holiday in the UK?
Aerolite's 3-piece and 4-piece hard shell sets are designed for UK family travel. Both feature matching ABS hard shell construction, 4 dual 360° spinner wheels, built-in TSA locks, and smart organised interiors on every case. The 3-piece covers couples and smaller families; the 4-piece adds a 32" extra large for bigger families and longer or more adventurous trips.
Why should families buy a matching luggage set instead of individual suitcases?
A matching set is easier to spot at the carousel, stores more compactly at home (the cases nest inside each other), and gives every family member the same quality wheels, locks, and interior organisation. It's also better value than buying individual cases separately, and the coordinated look makes the whole experience feel more intentional and exciting for the family.
What sizes come in a 3-piece luggage set?
The Aerolite 3-piece set includes a 21" cabin case (55x40x20cm, expandable to 55x40x23cm, 38.8–44.6L), a 24" medium case (67L), and a 28" large case (100.8L). The cabin case fits Ryanair Priority, Wizz Air, Lufthansa, and most major UK and EU airlines.
What does the 4-piece luggage set include that the 3-piece doesn't?
The 4-piece set adds a 32" extra large suitcase (87x55x34cm, 144.1L) to the cabin, medium, and large. This is the piece families of 4+ have been waiting for — enough space for everyone's full wardrobe, holiday extras, and the gifts and shopping that always seem to appear on the return journey.
Do luggage sets nest inside each other for storage?
Yes — both Aerolite sets nest neatly. The 3-piece stores entirely inside the 28" large case. The 4-piece stores inside the 32" extra large. Between holidays, your entire family's luggage takes up the space of just one suitcase.
Is the cabin case in the luggage set approved for Ryanair?
Yes. The 21" cabin case measures 55x40x20cm unexpanded — the exact Ryanair Priority overhead allowance. Expand it to 55x40x23cm for Wizz Air Priority, Lufthansa, TUI, British Airways, and Jet2. It's the most versatile piece in the set, and the one that travels with you in the cabin on every flight.
