Flying next week - any tips while pregnant??

ludali

I have to fly for work next week - and will be in my 9th week...  I usually take plenty of Airborne leading into a flight, but have read to not use it during pregnancy.  I will take the usual precaustions - hand sanitizer and stay plenty hydrated - but any other tips/tricks that can be shared?  I hope my prenatal has boosted my immune system enough that I won't pick up anyone's cold!!

Thanks!!
