The DS comes with two styluses (stylii) so you can afford to lose one
Your DS will last about 16 hours with a full charge, so yeah, happy gaming on your flight!
You might also want to invest in a DS USB charger cable since Europe has so many funky plugs your original DS charger may not fit the local socket. USBs at least are universal, and they are also fast in charging the battery - and of course, you can find USB-equipped computers everywhere!
