Travel insurance plans do not require that the entire traveling party be on the same policy. Some travelers may choose to be covered on the same policy, others may choose a different policy and some may choose not to have a policy at all. Plans with trip cancellation and trip interruption can cover unforeseen events that happen to a traveling companion, regardless of whether or not the traveling companion has a policy. A traveling companion is somebody who shares the same travel itinerary. There may also be advantages to selecting different policies. For example, if the traveling party includes people of significantly different ages, then it may be more cost effective to get separate travel insurance quotes and compare the cost of the premiums. Some plans have per policy limits on benefits, which can make separate policies a more prudent option. This may not always be the case, which is why it is important to compare different travel insurance plans and options. Always refer to the certificate of insurance for details.
