It's a laptop, designed to be mobile. Mine's been across the globe a few times the last 13 years. So there's only really physical damage to worry about. Well, that and moving from air conditioned airport straight to a highly humid climate outside. This can actually trigger the moisture strips inside.
I live in South Florida and here's all about extreme temperatures.
My MBP goes from a cold house to hot and humid, then to a hot car that cools down to 68ºF, then back out to hot and humid, then into a cold office and back to hot and humid.

Since 2007 none of my devices have had any problems related to these conditions.
 
It should be fine in a good protective laptop bag. Personally, I don’t take a laptop on vacation anymore. I just want to relax. Having no carry on luggage also makes boarding and departing a plane much nicer. It’s amazing how relaxing it is. Also a leg room bonus.

never had your checked bags lost or spent hours at baggage claim?

I think the total opposite – not checking any luggage feels way more relaxing. The stress of them misplacing your bag or breaking something, the interminable wait at the airport for your stuff to come out delaying the entire holiday ... I'd rather just jump off the plane and get straight on with my life.

I have. I went on a 2 week vacation to the tropics and Delta sent my luggage to Alaska. They gave me a t-shirt that said "Delta Team" or something similar. I got the luggage three days later. Not the best experience.
 
I always carry-on my backpack with all my electronics (laptop, iPad, camera if bringing one...) and make sure you have at least one change of clothes in your carry-on. Don't pack all your clothes or other essentials you can't easily buy more of in checked luggage. If you carry-on your laptop you'll know exactly what it's subjected to while traveling. They usually let you have your backpack under your seat, separate from the other carry-on bag you're allowed that has to go in the overhead bin.

Yikes, did not realize this! Would putting it in a plastic bag help with this at all?

You would think all people would do this but amazingly and disturbingly not. Some place more importance on having room for toiletries in their carry on bags.

I believe you.

However, my experience is just as valid and real. Never any direct contact with liquid, my MBP's LSIs were set off in the Apple Care period and warranty for a SMC fault denied due to this. Apple wanted €1,300 for a logic board replacement! Prior to this, I had flown in via SIN A/port spending some quality smoking time in the lovely Sunflower Garden before re-boarding. Right. So this was the only place I can think of causing the moisture internally. Very cold A/port to balmy highly humid environment. From memory, the garden was watered at the time also?!

Same moment in time I recall nervously watching my m4/3 lenses developing moisture droplets b/ween the glas elements removing them from my bag. Not weather resistant lenses and I forgot a plastic zip lock bag exactly for this situation.

So given all variables that can exist in combination, YMMV applies.

Unfortunately I didn't and the LSIs were triggered internally. Yer, a zip-loc bag is often used with camera gear to let the body/ lenses 'acclimatise' to extreme conditions.
 
Whether or not you bring your laptop should depend on your computing needs and luggage space. If you only need to check email and browse MacRumors, then you should bring an iPad and leave your MBA at home. However, you wrote:

"I still like to do research and work in my down time."

Thus, you've answered your own question! Take the MBA.
 
Hi All,

Really silly question but at the start of the year I purchased my first MacBook and I absolutely love it. I am shocked at how quick it is and the battery life and I take really good care of it. I am now going on holiday tomorrow (I normally take my laptops with me) and in debate whether to take it along with me or to take my old laptop (bigger and heavier)? I have a case for my MacBook but I am nervous that taking it with me as I do not want the the performance or battery to drop as it has remained as good as it was out of the box so far.

Can anyone advise if I am being over the top here or is it sensible to leave the device at home to keep it's performance?

Thanks!
Look at it this way - this is one of the most ridiculous things I've ever read. Just enjoy your laptop.

It's really not. You're right that it should be, and it once was. But now it's more like a complete head-off engine-rebuild, with the labour-cost to match.
Yes, it's difficult to replace now due to the thinness of the devices. But it's still the part you have to change after a few years. It's kind of a consumable part of a laptop.
