Had heaps of hassles with Virgin,Tiger and Jet Star
airbuses with 9 footer SUP they just will not fit ,and if your on a cheep ticket and have not declared sporting goods on purchase of your ticket your up for what ever figure they feel like.
Ive had to leave equipment behind a few times, so stay cool with a LOCAL.
What other reason and excuse do you need to go back

.
In saying this the larger planes and generally the country of origin carriers are only to happy to take your SUPs with out any problems
Remote places and transport to and from the airport is the worst
USE FULL TIPS
1 Put extra padding approx 1 to 2 foot on the bottom rail oppisite your carry handle shoulder strap.
2 Insure you have a carry handle in the middle of your board bag this is
very handy in combination with the shoulder strap and for transporting it on bikes walking on roofs,at hotels and around airports.
3 Travel with some light weight rope VB cord is always a winner and or straps
4 Travel with the minimal amount of bags as possible, insure you got the max for carry on.
