A portable tray for luggage has a support assembly, a ratchet assembly, a table, and a storage sleeve. The support assembly installs upon the telescoping poles of an existing handle assembly of luggage. The support assembly then allows a user to position the invention at a desired elevation from a supporting surface such as a concourse floor. The ratchet assembly allows a user to rotate the table from a stowed position, generally within the poles of a handle assembly, to a cantilevered position across the top of a piece of luggage. The user then unfolds the table of three plates into a flat shape, generally level but with at least two alternate angles. The invention fits into a storage sleeve placed within the handle assembly and within the luggage. The storage sleeve prevents luggage contents from entangling with the table and other components of the invention.
