Yael from Worldnomads.com here.
World Nomads provides single trip travel insurance coverage (not life insurance), but you can select specific duration that you require - so if you want to coverage for the entire duration of your trip to Europe (i.e. to ensure that both of your flights are covered), then you just include that in the dates selected.
You simply enter in your dates of travel and destinations on our website www.worldnomads.com to receive a quote. You can also buy more cover when you are travelling if you decide to stay longer. However, keep in mind there may be a waiting period if you purchase insurance whilst you are already outside your country of residence.
I suggest that you contact our customer services team if you have any specific questions about what's covered and not covered - you can reach them here:
