ORLANDO, Fla. -

Nearly two years after the Wizarding World of Harry Potter's opening, Universal parent company Comcast credits the attraction with "reliable growth" in guest spending.

Operating cash flow jumped 17.1 percent to $157 million, a measure of profitability Comcast says was primarily due to higher guest spending on tickets, food and souvenirs.

Revenue at the NBCUniversal theme parks rose 5.7 percent to $412 million for the past 3 months.

"(We) continue to be very bullish about Orlando, where you've got Harry Potter over a year old and doing great," said NBCUniversal Media chief executive officer Steve Burke.

"We continue to have healthy attendance in both Orlando and Hollywood, as both parks benefit from strong growth in international visitors," said Chief Financial Officer Michael Angelakis.
