Hello. Amy Mitchell here.
Hello, how may I oblige you today?
I promised to meet my sister on my niece's birthday party. So, can you please check for the flights from IAD to DEW?
Sure, can you please share your journey dates that you prefer to travel?
My journey will start on June 19th and I will be returning back on June 21st.
Ok, please wait for a while.
I need a single connection flight.
Can you please recheck your destination airport code?
My designation airport code is DFW.
 Thanks for sharing your details, we are unable to provide flight in between your journey routes due to heavy snowfall at destination airport.
Oh! That's very disappointing to know from you. Anyways, thank you for checking.
Thank you for reaching us.
