From 01 June 2016, the oneworld policy on accepting customers travelling
on separate tickets was changed. BA, along with our oneworld partners, has
implemented this change in policy which is as follows:
Only those customers that have separate tickets issued in the same
PNR/booking for flights operated by a oneworld partner, will be accepted
for through check-in
Customers that have separate tickets issued in separate PNRs/bookings
will not be accepted for through check-in, regardless of which carriers
they are connecting on to, including BA or any oneworld partner.
These customers, and their baggage, will only be checked in to the
destination showing in the system. No on carriage details are to be added
into the check-in system at any stage.
Please note that where a customer has separate tickets, the Most
Generous Allowance (MGA) rule for baggage does not apply and any
excess baggage will apply as per the ticketed sector for that ticket.
Customers that do have a ticket that has all journeys listed (a 'through
ticket'), will continue to receive the full benefits including through checked
baggage, most generous baggage allowance and full assistance if their journey
is disrupted.
The change oneworld made on 1 June means oneworld is applying the same policy that has been offered
by some other global airline alliances for a long time.
