Changes to a BA Issued DONE4
I am looking to change the first leg of a DONE4 from CAI-CMN-JFK to CAI-LHR-JFK. Wondering if anyone can confirm:
1. Is there any problem transiting through Europe assuming the ticket ends in Europe?
2. Right now there is no D availability through BA on one way flights. However, if booked as outbound legs of a return on BA there is D availability. Additionally there is D class availability on the BA flights if booked as oneway on Iberia or American. Would BA be prepared to ticket this?
Thanks in advance
