Mauretania departed Liverpool on her maiden voyage on 16 November 1907 under the command of Captain John Pritchard, and on the return voyage (30 November–5 December 1907) captured the record for the fastest eastbound crossing of the Atlantic, with an average speed of 23.69 knots (43.87 km/h; 27.26 mph).
On 23 December 1907, Mauretania was again at New York City and moored to Pier 54 in the North River when a squall with high winds struck, causing mooring posts on Pier 54 to give way.
Mauretania went partially adrift, and her bow swung around and struck several barges which were bringing her coal and taking off ashes; the barges Roan and Tomhicken and the boats Eureka 32 and Eureka 36 were damaged and the barge Ellis P. Rogers was lost.
In subsequent litigation, the Cunard Line was found liable for damages.


In September 1909, Mauretania captured the Blue Riband for the fastest westbound crossing — a record that was to stand for more than two decades.
In December 1911, as in New York City in December 1910, Mauretania broke loose from her moorings while in the River Mersey and sustained damage that caused the cancellation of her special speedy Christmas voyage to New York.
In a quick change of events Cunard rescheduled Mauretania's voyage for Lusitania, which had just returned from New York, under the command of Captain James Charles.
Lusitania completed Christmas crossings for Mauretania, carrying travelers back to New York.
Mauretania was on a westbound voyage from Liverpool to New York, beginning 10 April 1912, and was docked at Queenstown, Ireland, at the time of the RMS Titanic disaster.
Mauretania was transporting Titanic's cargo manifest carried by registered mail.
Traveling on Mauretania at the time was the chairman of the Cunard line, Mr A.A. Booth, who organised a vigil for the Titanic victims.
 In the spring of 1913 westbound transatlantic passage aboard Mauretania cost roughly $17 for third class passengers, as shown in the original ticket at right.
 
 In July 1913 King George and Queen Mary were given a special tour of Mauretania, then Britain's fastest merchant vessel, adding further distinction to the ship's reputation.
On 26 January 1914, while Mauretania was in the middle of annual refit in Liverpool, four men were killed and six injured when a gas cylinder exploded while they were working on one of her steam turbines.
Damage to the ship was minimal; she was repaired in the new Gladstone drydock and returned to service two months later.
