Inflight Event / Encounter Wake Vortex Encounter
General Physical Injury / Incapacitation
Environment - Non Weather Related; Procedure
Just leveled off at 29000 feet; passenger seat belt sign was on; flight attendants were beginning service. No turbulence at the time of the event; we hit a moderate jolt that lasted 3 seconds; strong enough that two flight attendants were hurt. I believe it was the wake from another aircraft. [One Flight Attendant] strained her right ankle. [Another Flight Attendant] complained of lower back pain. According to the lead flight attendant they were ok to continued to our destination but just to be sure he requested paramedics meet the aircraft.
