Have details regarding baggage limits/fees for each fare in your itinerary
Basically, each airline has a different baggage limit and some fares might even charge you. It would be extrememely useful to be able to click on each fare in your itinerary and find out what the the baggage limit is and what any extra baggage fees are to avoid any nasty surprises miles from home in some remote airport in Mongolia for example!
We would love to do this.
Are there any other sites out there that do this well that we could look at?
