Noted as being the prime breadwinner for trans-Atlantic shipping lines, third class aboard "Lusitania" was praised for the improvement in travel conditions it provided to emigrant passengers, and "Lusitania" proved to be a quite popular ship for immigrants. In the days before "Lusitania" and even still during the years in which "Lusitania" was in service, third-class accommodation consisted of large open spaces where hundreds of people would share open berths and hastily constructed public spaces, often consisting of no more than a small portion of open deck space and a few tables constructed within their sleeping quarters. In an attempt to break that mould, the Cunard Line began designing ships such as "Lusitania" with more comfortable third-class accommodation.
