thanks for further advice;
2 questions:
a. my Aadv miles 2 x 115K prem econ seemed refundable if canceled? so there's value in that...?
IB Avios don't seem as flexible if canceled?
b. Jul 15 BCN > MIA return shows 27K IB Avios x 2 = 54K econ, does IB have econ plus or similar with more room than econ?
thanks in advance, regards.
