Help me pack ten days in ryan air under Seat

30l hiking backpack & bumbag for phone and passport. Never had a problem with this.
Use compression packing cubes for clothes. Unpopular, but buy cheap underwear and chuck after wearing to make space for a souvenir or two.

This is the only option. Buy stuff when you get there even flip flops. You can't afford to take a pair of shoes extra.
Take only 1 cardigan, trousers and wear that. Aim to wash underwear every day so you wear a pair and wash a pair and have 1 spare. That's it. A pair of shorts, togs and then a few lightweight t shirts. Check accommodation where you are staying for things like usb sockets or buy a European charger from amazon as they are smaller. Do not bring any toiletries at all and buy everything locally.

Exactly this!

I bought one of these and it's brilliant:

Metz for Ryanair Cabin Bags 40x20x25 Underseat Cabin Bag for EasyJet, Ryanair, Wizz Air & More Travel Backpack for Airline Under Seat Carry-Ons, Recycled Polyester, Compression, Durable Hand Luggage : Amazon.co.uk: Fashion

Trainers, trousers, light jumper and jacket for the flight.

Buy tissues, toiletries and suncream when you arrive. I just take a coloured lipsalve and a cover up stick for blemishes on the flight.

Agree with taking a few laundry detergent sheets so you can run a wash, if you have facilities.

I also pack two panty liners per day so knickers can stay fresher.

Sleep naked, or use the T-shirt you
travelled in to sleep. Use hotel towels.

I always take a second pair of shoes - for hot places, I might travel in bulky walking sandals and then take a pair of ballet flats in my bag - knickers can be stuffed inside to save space.

Collapsible reusable water bottle also a must for me.

Take a cloth tote bag for your “daytime bag” - ideally one with a zip.

That's all we take each unless we are going diving.

One set on, one set clean. You literally need to think of it as what you need for a day.

Did ten days in Malta with a shade under a kilo including phone 😎

If you don’t go on holiday you save money too funnily enough!

My thoughts entirely.... And I'd never fly Ryan air!!

I never take more than that! Get some vacuum bags I’ve got a set on Amazon that come with a little USB powered vacuum absolute game changer

A tube of travel wash is your friend!

im currently carrying a pair of shorts, a pair of jeans, 4 tops, a dress, leggings, a spare bra, 7 pairs pants and a bikini on a trip, washing as and when, I don’t let it build. I’m not traveling by air so not sure if this will fit but you won’t need the thermal underwear i have!

Plan to buy as many items as possible at destination - toiletries obviously, swimwear/beach wear perhaps, sandals or flip-flops maybe, etc etc...

It is amazing how effective vacuum bags are even on quite dense items like tee-shirts.

3 pairs of linen shorts and three T-shirts is 9 outfits - get them in black, white, and grey or burgundy (or any other colour of choice). Monochrome for nights out dressed up with jewelry and mix and match for daytime. Wear your trainers and pack a pair of sandals. 1 bikini, 1 dress, 1 nightie, 5 pairs pants. Wear a pair of trousers, a jumper, and a light jacket. If you need a towel the microfiber ones from Decathlon are great.

I do it all the time. It's easy all clothes coordinate, roll them small and tight, take one pair of shoes (wear them to travel )

Primark do an amazing under seat bag. The wheels even pop on and off so to make it smaller when it needs to go in the size thingy. It was about £20

If you pack 5 though, you'd only need to wash them once mid-holiday. It doesn't take long at all! 10 mins work to save about £60 or whatever it is these days. Worth it for many I'd say. Cheaper even to buy more knickers if necessary at the destination.

You need to get yourself a bag like this

https://amzn.eu/d/09uBjcNy Or similar, there’s lots of different brands/colours. You can fit a surprising amount in them.

Use packing cubes, wear your bulkiest items, eg jacket and trainers, onto the plane. Neck cushion filled with underwear as PP suggested is a great idea. Refine toiletries and beauty products to the bare essentials, and decant them into the smallest containers possible.

Buy all toiletries in boots so you have a duty free bag for them.

I did this. And Ryanair were checking!

It's hard to say without knowing where you're going, but I'd do -

Wear - trousers, socks, knickers, loose long-sleeved shirt top, cardio (ideally merino as wool doesn't hold smells so shouldn't need washing), coat, sunglasses, sunhat, shoes.

Pack - swimsuit, 3 x thin tops, 5 x underwear, 5 x socks unless hot enough not to need them, no pjs (sleep naked), two thin dresses (I have ones like this which fold to nothing https://www.vinted.co.uk/items/3238447451-diane-von-furstenberg-100-silk-dress-uk-size-4), passport, toothbrush, toothpaste, Kindle, phone charger, socket adapter, small water bottle.

Rolling the clothes worked better for me than folding.

following as this will be me in 2 months time ;-)

This.

When flying wear a coat, jumper, cardigan, 5 t-shirts, leggings, jeans, 6 pairs of knickers (plus one to tie up your hair), five pairs of socks. It'll be uncomfortable but worth it.

I just can’t imagine paying and making the effort to go on holiday and standing there washing my knickers in the sink multiple times in the week.
I mean, just why?
Why make it so miserable? Just pay for a bloody bag.

What kind of holiday? City, beach, hike?

Beach is easy:
2x bikini
2x pants (you can wash in the sink)
1x sunscreen
3 dresses
Wear trousers and a top to the airport and trainers
Toothbrush and paste
Cleanser
Sandals
Book
Phone charger
Headphones

Done.

I flew Easyjet with an under seat bag only a few weeks ago, for 2 nights away.

I had:

• 1 pair thin trousers
• 2 t-shirts
• 1 shirt
• 1 set pjs
• pack-a-mac
• undies and socks
• tiny toiletries set
• hair straighteners

And my exact maximum dimension easyjet underseat bag was full. I had to pull the compression straps and squeeze it to get it to fit into the box at the gate (they were checking).

I didn't take swimming stuff or makeup, as it was too much of a squeeze. I definitely wouldn't attempt longer!

I don't bother with pjs when flying light, just wear that day's t-shirt to sleep in and wash frequently.
