Internet travel portal Ebookers ( EBKR) was drawing substantial buying interest on Friday, as speculation emerged that the company might become the target of a takeover bid.

According to Briefing.com, rumors are circulating that Ebookers could be the next online travel business to be acquired in the wake of USA Interactive's ( USAI) takeover of Expedia ( EXPE) and Hotels.com ( ROOM). The report didn't name a prospective buyer.

Shares of Ebookers, which is based in London, were climbing $1.82, or 15%, to $13.77 on more than three times the normal trading volume.

Briefing reported that talk making the rounds suggests that given the discount Ebookers trades at relative to Expedia's takeover price, any offer would come at a sizeable premium.
