Narrative:
En route to fak on J51, we were instructed to hold southwest on the flat rock 020 degree right, right turns, 10 mi legs, expect further clearance at XX50Z, about 1 hour away. We immediately notified ATC that we were slowing to holding speed. We discussed the holding pattern and entry and decided that a teardrop entry was appropriate, with an initial left turn to 350 degrees. At 20 DME the first officer began his turn to 350 degrees for the entry. Shortly thereafter, ATC gave us a right turn to 090 degrees, traffic northwest 15 mi. We immediately complied. We had both misinterpreted the holding clearance. We were planning to hold northeast, instead of southwest. We had discussed the clearance, pattern and entry and never caught our error. Nothing further was said by ATC. After a few more vectors, we were cleared by a new routing to phl. I usually don't have a problem with holding patterns. I always discuss patterns and entries with my first officer to be sure we're on the same wavelength. This time both of us missed the error. Maybe ATC could include in the holding instructions the initial turn just as an added backup to get us all on the same wavelength.

Title: ACR MLG STARTED AND IN THE WRONG DIRECTION.
Narrative: ENRTE TO FAK ON J51, WE WERE INSTRUCTED TO HOLD SW ON THE FLAT ROCK 020 DEG R, RIGHT TURNS, 10 MI LEGS, EXPECT FURTHER CLRNC AT XX50Z, ABOUT 1 HR AWAY. WE IMMEDIATELY NOTIFIED ATC THAT WE WERE SLOWING TO HOLDING SPD. WE DISCUSSED THE HOLDING PATTERN AND ENTRY AND DECIDED THAT A TEARDROP ENTRY WAS APPROPRIATE, WITH AN INITIAL LEFT TURN TO 350 DEGS. AT 20 DME THE F/O BEGAN HIS TURN TO 350 DEGS FOR THE ENTRY. SHORTLY THEREAFTER, ATC GAVE US A RIGHT TURN TO 090 DEGS, TFC NW 15 MI. WE IMMEDIATELY COMPLIED. WE HAD BOTH MISINTERPRETED THE HOLDING CLRNC. WE WERE PLANNING TO HOLD NE, INSTEAD OF SW. WE HAD DISCUSSED THE CLRNC, PATTERN AND ENTRY AND NEVER CAUGHT OUR ERROR. NOTHING FURTHER WAS SAID BY ATC. AFTER A FEW MORE VECTORS, WE WERE CLRED BY A NEW RTING TO PHL. I USUALLY DON'T HAVE A PROB WITH HOLDING PATTERNS. I ALWAYS DISCUSS PATTERNS AND ENTRIES WITH MY F/O TO BE SURE WE'RE ON THE SAME WAVELENGTH. THIS TIME BOTH OF US MISSED THE ERROR. MAYBE ATC COULD INCLUDE IN THE HOLDING INSTRUCTIONS THE INITIAL TURN JUST AS AN ADDED BACKUP TO GET US ALL ON THE SAME WAVELENGTH.
