No, Alcock and Brown were the first non-stop, period.
They landed in Galway on 15th June 1919; L34's crossing (from east to west) took place on 2-6 July 1919.
The airship did, however make a return flight to the UK a few days after arriving in New York, so can claim to have made the first transatlantic return flight.
