AirAsia Search Widens, No Emergency Signal Detected

The transcript discusses the ongoing search for a missing aircraft over 11,000 square nautical miles involving multiple countries' vessels and aircraft. Poor weather conditions are complicating the search, and no distress signal has been detected. An oil spill near Beltone Island is being investigated as a potential lead. The pilot's request to fly higher was denied due to heavy air traffic. Families of passengers are anxiously waiting for updates, and Air Asia's CEO has urged everyone to stay hopeful.

What did the pilot request to do before losing contact with air traffic control?

How are the family members of the passengers and crew members being supported during this time?
