In a statement to ABC News, Princess Cruise Lines said: "We are incredibly distressed by the situation, and our thoughts and prayers are with those onboard the planes and their families".
The Royal Princess left Vancouver, British Columbia, on May 11 and was scheduled to arrive in Anchorage on Saturday. Two others were missing, said Petty Officer Jon-Paul Rios, a Coast Guard spokesman.
Three people from the plane were found dead on Monday, and two that were missing were found dead by the Coast Guard on Tuesday. Multiple other passengers were injured.
That group was returning from a flightseeing tour of Misty Fjords when the crash occurred, Taquan said.
Ten people have been admitted to PeaceHealth Ketchikan Medical Center, a spokeswoman with the hospital, Mischa Chernick, told the Anchorage Daily News.
On Monday, two floatplanes carrying cruise ship tourists collided over Ketchikan, Alaska.
Cicchetti said the ship was not leaving as scheduled and there weren't any details as to how the accident would affect the rest of the trip.
Nine of the passengers on the Taquan Air plane were rescued and received medical attention with one passenger's condition still unknown, the release said.
Eleven people were inside a single-engine de Havilland Otter DHC-3 operated by Taquan Air when it went down as it returned from Misty Fjords National Monument.
"We are devastated by today's incident and our hearts go out to our passengers and their families", it said in a statement.
"At this time, we are in the midst of an active crisis response, and our focus is on assisting these passengers, the pilot, our staff, their families and loved ones and first responders", Taquan said in a statement. The Coast Guard is still searching for two passengers, one Australian and one Canadian.
In June 2015, a pilot and eight passengers died when a de Havilland DHC-3 Otter operated by Promech Air Inc. crashed into mountainous terrain about 24 miles (39 kilometers) from Ketchikan.
'In a remote area such as this, given our limited resources, we rely on our partner agencies and appreciate the support that good Samaritans have rendered to this point, ' said Capt. Stephen White, Coast Guard Sector Juneau commander.
It's not yet known what caused the collision between the two planes, but National Transportation Safety Board investigators are on their way from Washington, D.C.to the crash site. "It has also been confirmed there are five (5) fatalities from the independent air tour - four (4) Royal Princess guests and one (1) pilot".
