No. If you miss one leg of your ticket, the airline will consider you a ‘no-show’ and will automatically cancel you from any following flights. No refund will be available.
Flights must be taken in the sequence they appear on your ticket or eticket confirmation. If you plan not to take a flight as booked, please contact the airline as far in advance as possible to discuss your options. If you do not check in on time for a confirmed reservation, the airline may register you as ‘no-show’, which could result in extra charges and/or your whole flight itinerary being cancelled and/or render your ticket void.
