Lamar Odom Called for $25,000 Traveling Violation in New Lawsuit

Lamar Odom made over $114 MILLION during his NBA career -- but a travel agent says the guy refuses to fork over a measly $25,000 for plane tickets ... and now he's suing.

Omar Rahmani claims he booked all sorts of trips for Odom between March '18 and June '18 -- from Florida to Vegas to New York ... even a flight to Hong Kong.

But, after racking up a $25,629.47 bill ... the NBA star refused to cut the check to Rahmani, his lawsuit claims.

Now the guy has filed a lawsuit in L.A. County Superior Court accusing Odom of breach of contract and fraud ... and he wants all of the cash plus punitive damages.

As for Odom, he doesn't seem too bothered by the lawsuit -- he's been training his ass off in New York to get ready for the Dubai International Basketball Championship which goes down in Feb.

The 39-year-old has been gunning for a pro basketball comeback ever since he recovered from his drug overdose in Nevada back in 2015 when he suffered 12 strokes and 6 heart attacks.
