American Express have a fantastic offer of 42,000 Bonus miles for taking out their Platinum Chargecard, when you are referred by an existing cardholder. As a UK Platinum Cardholder myself, i would be very happy to refer anyone who is considering or would like to take out a Platinum card, feel free to PM me with your email address and i will send you the referral link. Here's some info on the American express Platinum Card = www.americanexpress.com/uk/platinum-card/ I have held the Platinum card for over a year now and travel several times a month and can honestly say it is a brilliant thing and an absolute must if you travel regularly. It is not a credit card, just a chargecard(with no limit) so 30 days with no interest, you just clear down every month, and for the £300 annual fee you get The two free Prestige level priority pass cards (Highest level, worth £259 per card), worlds best travel insurance(also covers your spouse when travelling with you), Hilton Gold Status (and equivalent with Raddison, Starwood, Hertz and others) 24-7 concierge free of charge (i have used this to arrange gifts for interntational business clients, booking tickets to sold our concerts and to get tables at restaurants with several month waiting lists), and access to Amex fine hotels of the world programme (5* hotels for phenomenal rates aswell as AMEX only benefits such as complimentary room upgrades and guaranteed early check in and 4pm checkout), aswell as perks like fast track airport security at Toronto airport just for showing your Platinum card make this a great thing to have. BA also regularly run offers exclusively for Amex Platinum CardHolders whereby you can exchange your AMEX miles at 2 for 1 for BA Miles with no upper limit, so those 42,000 are actually worth 84,000 miles (approximately a complementary business class return ticket to NY)! I honestly cannot recommend this more highly to anyone. If you'd like the bonus 42,000 miles and are UK based, please PM me and i'll happily send you the referral link. Any questions on the card, Best wishes.
