Hi, Katrina from WorldNomads.com here.
As you've seen, we currently only offer set durations for our travel insurance plans, however we give you the flexibility to extend while you're traveling.
The duration of cover offered will differ depending on your country of residence, which you haven't specified.
Either way, you have 2 options:
1. Buy a 3 week duration plan now, and this will cover you for the full duration of your trip.
2. Buy the 2 week plan now, then after you have started traveling, you can extend this plan through your WorldNomads membership.
If you'd like to ask specific questions about our travel insurance coverage, please do contact our customer services team direct, who are more than happy to help-
Safe travels about 7 years ago
