There's only one type of stroller you can take onto the plane with you (the Quick Smart) because it folds up to umbrella length and goes into a bag. So, there's an option.
If we go OS I'll be taking this instead of the buggy we checked in last time...it got left behind in Dubai, hung around in London for a while (well after we'd left there for our connecting flights!) and eventually joined us in Waterford, Ireland, AFTER the wedding we'd gone to Ireland for and with my storm cover missing (but a leg pocket thing stashed into it...it wasn't ours but is now!). Luckily it was a first gen Phil and Ted's, because it had also copped a beating and would have been broken if it had been the newer type or any other pram/stroller!
I picked up my QuickSmart last year at a market for $5...I got lucky, and you might too - oppies, markets, depending on what time you have
