I've never flown internationally, so I don't know if this is the norm or not. I've gotten 2 calls from Air Tahiti Nui since booking my flights (in November). Our flight from Papeete to Bora Bora was bumped up an hour and our flight from Bora Bora back to Papeete was also bumped up an hour. I chose our initial flight times based on check in times and convenience for us. An hour isn't a huge deal, I was just wondering if this is common. Our flights are in late July/early August.
