IB Plus or BA Executive Club?
Looks like this year I'm going to have to do a fair amount of BOG-LON flying, so instead od requalifying on LATAM I'm thinking of switching to either IB or BA. I'm guessing IB would make more sense as all ex-BOG flights go via MAD, but it looks like slightly less flights are required to get emerald on BA than on IB.
Are there any other differences I should be aware of?
Also, my first flight this year will be in January. Can I fly w/o putting in a number and add it retrospectively after March to hit the qualifying period?
Any thoughts welcome!
