You might, but then again, you might not!

The last couple of times I have checked the fare for a domestic business class purchase on VA through the Acccelerate Portal, I have found equal or better promo rates on the regular website!

I also want to be able to cancel flights to refund as cash - not credit bank. VA makes you ring up to do this, which is a pain....

Incidentally, IIRC, the QF business system recorded expenditure, but not cancellations of some flights, so was way over estimating annual spend on my company account!

In a small business it may or may be better to stay light on your feet and go for best fare on the day, promos, double points and credit offers, etc....it's not easy do to the maths committing too either QF or VA!
