Sister reunion after 10 years

Lani • Married. 3 daughters.
My sister and I haven't seen each other in 10 years due to funds and being on the other side of the country (arizona and new york). She's 5 months pregnant and getting married next month. I've bought my plane ticket to surprise her but I don't know how to do it. Any ideas? Like I was going to call her and talk to her and walk through her door on the phone with her. And have her freak but if any of you have any suggestions, i'd like to hear them.
