Artandco - am in awe of the ability to do that hand luggage.
I kind of have the opposite issue though, it is actually hand luggage that doesn't work too well for me. DS is a wheelchair user, with only two adults once you get past security and luggage trolleys, hand luggage becomes a nightmare. Any luggage plus public transport is just a total no go as it takes two adults to do DS, wheelchair and stairs, (even if at that time DS is ok to get up and walk them, you still need free hands in case he trips). You run out of hands. Particularly if DD also wants to hold one.
Backpacks are ok but you tend to hit other people with them because you are often focussed on DS manoeuvring securely and safely. Wheelie suitcases mean you can put them down when DS needs help, but what with wheelchairs and wheelie suitcases, as a group it becomes quite difficult to move around the airport.
I would rather not be washing clothes. Most likely I will be washing night clothes and bed protectors anyway (can't put those into hotel laundry), I rather keep it at that.
We did cabin luggage only this year short haul. It wasn't easy. We're actually paying the extra to stick a couple of bags in the hold this year.
Hand luggage only kinda pointless anyway from a wait at the other end perspective. If they choose to check DS' wheelchair at the gate you may have to wait for it at baggage reclaim anyway depending on the airport.
We are looking to travel long haul. There is a certain amount of stuff that needs to travel hand luggage because it is necessary or difficult to replace if it gets lost like first aid kit, medicines, special cutlery and night-time nappies (which are bulky at DS size). The thought of taking all the additional stuff people say you need to make the long haul flight bearable is unpalatable to say the least. I would rather slim down hand luggage.
Thanks Milly its good to know the upside and downside of flying minimal handluggage
