Long story short, my FI and I didn't end up booking the same flight to Honolulu. I am leaving LA and arriving there at 7:30pm. My FI is leaving from San Diego and arriving at noon (there's a connection in LA anyway). We both bought tickets from Delta and by the next day my FI decided to start booking his flight the flight I was on was $400 more expensive than the original price.
My question is, do you think if I call Delta and explain to them that we are on our honeymoon and would like to be together they will be nice enough to help without a heavy rebooking fee?
