We have 14-16 days alloted for our trip to Tikehau via Papeete this coming summer. Our home is near Washington, DC. We can depart from DC as early as Jun 21st, but must be home by Aug 6th. In general, what are the least expensive days of the week for travel to/from Papeete? I'll get cost info on RT flight Papeete/Tikehau once I decide on travel days. Thanks.
