Narrative:
Initial climb out of bwi told to climb at 'best angle' passing 15000 ft until FL220. At FL220 on frequency 120.65, slowed (by ATC) to 250 KTS. Said for 'spacing to cvg.' then when requested higher altitude (filed for FL260) and normal speed, cleared to 300 KTS or greater, but held down to FL220 due to overhead traffic creating 'condition red.' this was after numerous off course vectors. Several other aircraft also received 250 KT restr. Seemed to get better handling afterwards, but altitude kept at FL220. 1300 pounds over burn on fuel.

Title: A B757-200 JUMP SEAT OBSERVER RPT ON TFC CONGESTION FROM LDN WEST THAT KEPT THE ACFT DOWN TO FL220 WITH A RESULTING FUEL BURN OF 1300 LBS OVER COMPUTER FLT PLAN FUEL ON FREQ WITH ZDC.
Narrative: INITIAL CLBOUT OF BWI TOLD TO CLB AT 'BEST ANGLE' PASSING 15000 FT UNTIL FL220. AT FL220 ON FREQ 120.65, SLOWED (BY ATC) TO 250 KTS. SAID FOR 'SPACING TO CVG.' THEN WHEN REQUESTED HIGHER ALT (FILED FOR FL260) AND NORMAL SPD, CLRED TO 300 KTS OR GREATER, BUT HELD DOWN TO FL220 DUE TO OVERHEAD TFC CREATING 'CONDITION RED.' THIS WAS AFTER NUMEROUS OFF COURSE VECTORS. SEVERAL OTHER ACFT ALSO RECEIVED 250 KT RESTR. SEEMED TO GET BETTER HANDLING AFTERWARDS, BUT ALT KEPT AT FL220. 1300 LBS OVER BURN ON FUEL.
