In 1997, Gudmundur Kjærnested decided to start a shipping company to serve the Iceland route.
 Then an Icelandic citizen, educated in the United States, and having worked at Van Ommeren shipping for seven years, he was familiar with the route and its history.
 Kjærnested's college roommate at Babson College, Brandon C. Rose, came from an affluent family whose yearly business revenues were estimated at $200 million per year.
 Rose offered to back the company, and together they started the two companies TransAtlantic Lines LLC and TransAtlantic Lines Iceland in February 1998.
 The two were originally even partners in both ventures.
 Shortly thereafter, they accepted an offer from shipping company American Automar to purchase 51% of the company, along with a never-exercised option to buy 51% of another Icelandic company largely owned by Kjærnested, Atlantsskip.

The company made several preparations to bid for the Iceland contract.
 Rose secured a million-dollar letter of credit from the State Bank of Long Island to back early operations.
 The company did not yet own any ships, but did secure four letters from U.S. shipping companies pledging to supply vessels sufficient to cover the charter requirements.
 One of the pledged vessels was the supply boat Native Dancer.

Eight bids for the 1998 U.S.–Iceland run were solicited by the Military Traffic Management Command on 30 January 1998, and six bids were received.
 Observers speculate that the bids were from the Icelandic company Eimskip, Dutch shipping company Van Ommeren, Atlantsskip, TransAtlantic Lines, and TransAtlantic Lines Iceland.
 In September 1998, the Military Traffic Management Command awarded 65% of the Iceland contract to TransAtlantic Lines Iceland, the lowest overall bidder, and the remaining 35% to the TransAtlantic Lines LLC, the lowest bidder among American shipping companies.
 The portion awarded to TransAtlantic Lines LLC had a cumulative total value of $5,519,295 and was set to expire by 31 October 2000.

Within a month, TransAtlantic re-flagged Juno to the United States and renamed it Geysir at the Port of Jacksonville.
 In response to the awards, the government of Iceland lodged a protest with the U.S. State Department, arguing that "TLI was not a true Icelandic shipping company" and "lacks the necessary experience, technical capability, financial responsibility, and material connection with Iceland"  Shipping companies Van Ommeren Lines (USA) and Eimskip of Iceland, which had previously serviced the Iceland route, sued the United States protesting the award.
 The district court found for Van Ommeren and Eimskip, requiring the Army to restart the bidding process.
 TransAtlantic appealed the decision, and on 11 January 2000 the Court of Appeals reversed the lower court's decision, finally securing the contract for TransAtlantic.

On 4 December 2000, members of the Coast Guard Marine Safety Office observed an accidental discharge of approximately 250 US gallons (950 l) of diesel fuel from one of Geysir's tank vents into the Elizabeth River.
 In 2001, the Coast Guard of Iceland detained the vessel leading the American Bureau of Shipping to temporarily revoke the ship's safety construction certificate and safety equipment certificate.

  On 8 September 2006, with the Cold War well over, the United States ceremonially disestablished Naval Air Station Keflavik and its twenty-three tenant commands, a process begun that March.
 The closure marked the end of the 65-year military presence, the last 45 years of which coordinated under the United States Navy with activities of the National Guard, Air Force, and Army.

On 3 February 2009 the United States Transportation Command awarded TransAtlantic a $15,078,334 contract to carry cargo between the United States and the terminal in Praia da Vitoria, Azores.
 This contract, serviced by the Geysir, is expected to be completed by 29 February 2012, and was a 100 percent Small Business Set Aside acquisition with two bids received.

As of 2010, the ship is owned and operated by TransAtlantic Lines LLC.
