A West Orange woman is suing an airline because she says it failed to properly inform passengers that live television and Internet service aren't available on all flights.

Cary M. David filed a $5 million class action suit in federal court in Newark alleging United Airlines failed to notify passengers that WiFi and DirecTV are inoperable when the flight is outside the continental United States or flying above a body of water.

David paid $7.99 to order DirecTV on a four-hour flight from San Juan, Puerto Rico to Newark on Feb. 21, but says the satellite television service only operated for the final 10 minutes of the flight, NorthJersey.com said.

United filed a memorandum to dismiss the suit on Friday. The airline contends information about when the services aren't available are shown on a seat-back monitor before customers confirm their purchases. It is also available on the airline's website.

David filed her suit March 13, according to TopClassActions.com.
