The flight isn’t what I’d be worried about. You’re going to a place where few if any will be wearing masks in public and the majority is not vaccinated. I’d be worried about the hotel, dining, and attending the ceremony since you’ll be indoors with them. By summer hopefully the spread of the virus will be lower.
If you do go I suggest using only N95 masks. There’s a reason they only come with the headband instead of the earband, it’s because that makes a tighter seal.
