Great question! There are a few competitors - check these when you have time just to have a better idea about the environment: CryptoCribs, Winding Tree, TravelCoin, Smart trip, Lockchain ICO, Loyyal (partially - loyalty platform also covering traveling). They are different from TLT in that they are single businesses or platforms; they are not a consortium aiming to work with existing industry leaders, they all rely on public blockchain platforms that suffer from scaling issues, and they are practically limited to niche use-cases.
