I am in need of an expert!
I have two Gs booked on an upcoming flight. I would like to change the date of travel. The new date only has 1 G available but plenty of reward availability in PE. Am I able to switch the flights, and downgrade one of the passengers to PE whilst keeping the other in UC?
A further question -- presumably one gets a refund of the difference in miles if this happens (minus an admin fee?!)?
I suppose I am asking about a particular case of a more general question -- namely, can you put different passengers in different cabins on one booking? I am curious as to what the 'your itinerary' page on the website looks like if this happens.
Thanks very much for any help.
