Class Problems

[Azathoth]

When trying to construct a class object containing another class object, I get the error:

"no matching function call to "PlaneId:laneId
candidates are: pLaneId:laneId(const PlaneId&)
PlaneId:laneId(const std::string&, int)"

Here are my two class files:

//  File:  Planes.h

#ifndef Planes_h_
#define Planes_h_

#include "PlaneId.h"

enum PlaneStatusType { UNASSIGNED, IN_RANGE, IN_LANDING_QUEUE, IN_TAKEOFF_QUEUE, LANDED, 
		       TOOK_OFF, EMERGENCY, CRASHED };

class LandingPlane {
 public:
  LandingPlane( PlaneId const& id, int scheduled_minute, int minutes_until_arrival,
		int fuel_minutes_remaining, int num_passengers )
  { m_id = id; m_scheduled_minute = scheduled_minute;
    m_minutes_until_arrival = minutes_until_arrival;
    m_fuel_minutes_remaining = fuel_minutes_remaining;
    m_passengers = num_passengers; }
  
  PlaneId const& id() const { return m_id; }
  PlaneStatusType status() const { return m_status; }
  int scheduled_minute() const { return m_scheduled_minute; }
  int on_ground_minute() const { return m_landed_or_crashed_minute; }
  int minutes_until_arrival() const { return m_minutes_until_arrival; }
  int fuel_minutes_remaining() const { return m_fuel_minutes_remaining; }
  int runway_number() const { return m_runway; }
  int minutes_in_queue() const { return m_in_queue_minutes; }
  int num_passengers() const { return m_passengers; }
  int delay() const { return m_landed_or_crashed_minute - m_scheduled_minute; }

  void increment_minute( );
  void assign_to_runway( int runway_number );
  void land_plane( int minute );
  void crash_plane( int minute );

 private:
  PlaneId m_id;
  PlaneStatusType m_status;
  int m_scheduled_minute;
  int m_landed_or_crashed_minute;
  int m_passengers;

  int m_minutes_until_arrival;
  int m_fuel_minutes_remaining;
  int m_in_queue_minutes;
  
  int m_runway;
};

//  File:    PlaneId.h

#ifndef PlaneId_h_
#define PlaneId_h_

#include <string>
using namespace std;

class PlaneId {
 public:
  PlaneId( string const& airline, int number ) 
  { m_airline = airline; m_number = number; }
  string const& airline() const { return m_airline; }
  int number() const { return m_number; }
  void set_airline(string a) { m_airline = a; }
  void set_number(int n) { m_number = n; }

 private:
  string m_airline;
  int m_number;
};

bool operator< ( PlaneId const& p1, PlaneId const& p2 )
{ return p1.number() < p2.number(); }

bool operator== ( PlaneId const& p1, PlaneId const& p2 )
{ return p1.number() == p2.number(); }

#endif

I get this error without even attempting to create an instance of the object...any ideas?

Apparently I just needed a default constructor in PlaneId...disregard.
