David Moyes had every senior player available to train at Rush Green on Wednesday ahead of the flight to Athens for Thursday's UEFA Europa League Group A tie with Olympiacos.
The manager reported a clean bill of health as Aaron Cresswell and Maxwel Cornet trained alongside their teammates ahead of the trip to Greece for matchday three.
Cresswell and Cornet were both absent from the squad which lost at Aston Villa in the Premier League on Sunday, but travelled alongside their fellow Irons on Wednesday afternoon.
Birthday boy Divin Mubama, who turned 19 on Wednesday, was also on the plane, meaning the Hammers headed to southern Europe with strong squad for Moyes to choose from.
Club photographer Arfa Griffiths was on hand to capture Wednesday's session on camera.
The squad will travel direct to Georgios Karaiskakis Stadium in the port city of Piraeus on arrival, where manager Moyes and Greece international Dinos Mavropanos will speak to the media while the squad take in their surroundings.
Thursday's tie will be broadcast live in the UK by TNT Sports, with kick-off at 5.45pm GMT (7.45pm in Greece). More information on how to watch can be found by clicking here.
