New to this so have a few (possible) numpty questions.


I have an Evoucher from BA and would like to use it for this RTW trip.
Q1 I assume I have to start the trip with a BA ticket (though not necessarily from UK) ?
Q1a I would have to ring BA to book.


I get several errors on certain routings saying "cannot find a flight on this date" when there are clearly flights.
Q2 Is this because there is a special ticket bucket fare that is truly not available or is the tool wrong?

Example KEF-Lon in Jan 2023-No economy fare but there is Business-Then looking at the detail it says this flight has no Business seats so you are in Economy!
Example 2 DUB-Lon-No flights!


Odd behaviour?
I get an error:-
There is an unexpected issue when requesting a price for this itinerary. Please try changing a flight, date, cabin or city/destination.

When I change the carrier (from IB to BA in this case) it all works fine.
Anyone know why?

Thanks
