Selecting only three travel solutions is like tasting three types of pasta from the same producer and claiming to have done a complete market analysis.
Who chose these three, and for what specific reasons? Without a clear methodology for their selection, the why of these choices is missing.
A true comparative test needs more diversity; imagine if these three apps target the same type of traveler, it wouldn't teach us anything new about the rest of the market. We would just end up with a list, not a real comparative study that can guide us toward an opportunity.
