Earlier this month we heard about the Citi Executive 100k offer, which is still around, and just today (HT to View from the Wing) there is another great offer. The Chase British Airways Visa Signature (application page here, non-affiliate link) offers 50k Avios after $2k spend in 3 months, then another 25k Avios after $10k in purchases within the first year, then another 25k Avios after another $10k in spend in a year. So basically you get the 100k Avios if you spend $2k in 3 months and $20k total in a year. Also, if you spend at least $30k in a year from account opening, you will earn a Travel Together Ticket good for two years when you redeem for a flight on British Airways. (per the website, taxes, fees and carrier charges are approximately $682-$1250 per adult in economy or $1250 in business class based on travel from Seattle to London…BA is known for their high fuel surcharges).
This is not as good as the Citi deal, which offers 100k AA miles after $10k of spend, albeit in 3 months, at least not to me, but it might make sense for some people depending on how you spend and who you want to fly.
