body: Suppose a customer in the UK books multiple flights with a Canadian airline via telephone. 
  
  
  Say the flights include:
   - Flights from the UK to Canada
   - Flights from the USA to Canada
   - Flights from Canada to the UK
  
  
  On the telephone, the customer gives the details of the flights and receives a *single* quote (in CAD) for all the flights combined. The customer then pays using a debit card over the telephone. Later that day the customer receives an email confirming all the flight bookings. The booking information includes seat numbers.
  
  
  6 weeks later, an auditor at the Canadian airline calls the customer and says that the price paid was incorrect. The auditor says that there was a mistake and one leg was not included in the quoted price. The auditor says that despite the confirmation email the customer will not be able to travel on that leg unless the additional amount is paid.
  
  
  Are the actions of the Canadian airline legal? What action should the customer take?
  
  
  
title: Is it legal for a Canadian airline to alter the price of a multi-flight booking after the initial payment and confirmation?
