I thought you were going to say you’re on one item only - BA hand luggage allowance is huge!
I take up to 40-50 flights a year. I can do rucksack only for up to a week, and rucksack + cabin suitcase for up to 3. I only ever take checked luggage if travelling long-haul or somewhere I won’t have access to regular toiletries / specific energy snacks I need for work.
4 days (even if that means 8 outfits) can totally be done on hand luggage only.
I’ve just come back from 2.5 weeks away and packed roughly as follows.
Cabin suitcase:
- 3 pairs long summer trousers
- 1 pair shorts
- 4 dresses
- 5-6 tops
- 2 jumpers (thin Primark type ones)
- 2 pairs of sandals - wore trainers on plane both ways
- Complete work outfit consisting of pant suit, top, blazer and flat shoes
- Underwear, socks, bras (about 4-5 of each)
- Bikini
- Hair straighteners
- Make-up bag (brushes, powders, mirror, hair ties, razors, cotton pads etc, see below for liquids)
- Chargers - phone, iPad, laptop, kindle, battery pack, headphones - these add up
Backpack:
- All tech
- Wallet
- Another jumper for plane
- Books + work gear
- Water bottle
- Liquids (took only perfume, moisturiser, foundation, and some liquid medication. Rest can be bought cheaply at destination)
I am already unpacking otherwise I would attach a photo. I don’t get why people always book hold luggage for short trips (unless for pure comfort, in which case fair enough!).
It can be done OP. The suitcase doesn’t need to close nicely while half-empty like you see on TV. You might need to squeeze it a bit, but it will fit.
You can rewear stuff. You can give it a quick wash at the Airbnb in the evening, get excess water out by tightly rolling and squeezing stuff into a towel, then air overnight and it will be dry by morning.
When I don’t have access to a washing machine past those 7-8 days’ worth of clean clothes, it’s a great and easy solution. Takes 5 mins tops.
Edit to add 2 pair of PJs to that list - have just taken them out of the suitcase 😂 and to second the idea of rolling stuff into footwear - socks, underwear, other small bits. Wrapped in a clean plastic bag if you already need to do it on way out. Way back who cares, they’re already going straight into the laundry.
