I wrote earlier today that Barclaycard Arrival Plus® World Elite Mastercard® has a new best ever signup bonus. You can get 70,000 bonus miles when you get the card, and the annual fee is also waived. But many people may have already applied with the previous best bonus which was available until yesterday. That bonus gave you 10,000 miles less.
If you already applied recently, you can still take advantage of this new better offer. There’s already some data points (1, 2) where they matched a cardholder to the new offer with 10,000 more miles. Doesn’t hurt to call in for an extra $100. You could also trey secure message, but a call is quicker.
Let me know if it works out.
