What was your Gold review date? Your gold membership typically expires at the end of the month and not the beginning, and god benefits are valid for 2 months after your tier review date. So, if your review date was 30th April and you didn't requalify for gold, you can continue to enjoy Gold benefits until 30 June.
My guess is that you should be good on your inbound as well if you are getting Gold benefis on your outbound since your travel dates are in the same month.
