If you want to keep list of trips you’ve took we recommend to use trip type.

You can specify itinerary metadata for all itinearies of the trip like this:

from = "FRA"
to = "GIG"
date = "2012-11-17"
type = "flight"
data = "DE6080"

from = "Rio de Janeiro, BR"
to = "São Paulo, BR"
date = "2012-12-14"
type = "bus"

from = "GRU"
to = "PTY"
date = "2013-01-30"
type = "flight"
data = "CM724"
transit = true

Such data will be preprocessed automatically and extra fields will be calculated:
