In travel, if the site is e-com site (rather than affiliate or adsense site), the most searched keywords are information type keywords. The best converting keywords are, however,long tail keywords.
The challenge is that after ranking and getting traffic for most searched keywords (info gathering stage), the site itself is trustworthy and has a good UI/UX so that when visitor is in the buying stage, they return to the same site to buy.
The price, whilst important, is not everything. For expensive and slightly uncertain purchases such as holidays in a country where visitor may not know much about, many would rather pay a bit more to have peace of mind than go for the cheapest deal with less confidence in its supplier.
It seems that your client is failing on this "second step".
