hi folks, My family of 4 (toddler &infant) have an upcoming trip to Bali, Indonesia coming up in a couple weeks. i am want to hear from folks about what my choices are, as I am hearing all the news about the possible eruption of the volcano

we are flying jfk- del via emirates - saver fare & dps-jfk via emirates - flex plus fare ( upgraded to J with miles)
del-dps we are flying MH on a separate booking
I am thinking of going to another location for the vacation. i do have trip insurance by allianze

i have a few questions

Is it worth calling emirates now and changing the location of my return from bali to say like cebu,phillipines or another destination in the far east? has anybody done this ?

what if there is an eruption before i get to bali, how flexible is emirates to change my departure location to another location?

should i cancel my return as it is flexplus and do another booking?

thank you
