Good TAP one way business class flight deals to the USA

TAP Air Portugal is still offering some excellent one-way fares to the United States from London, Manchester and Dublin.

How cheap?  How about £573 one-way in Business Class?

For example, Dublin to New York on 17th September is £620 which is reduced to £573 using the code TAP10FLY3006 before 30th June.

London to New York is £710.

From Manchester, the flight is £715 on the same day.

Adding the code is fiddly.  As far as I can tell, you need to get a quote WITHOUT using the code and then click in the top menu to go back to the ‘Search’ page.  You will then see a tick box marked “I have a promotion or a congress code” which lets you input TAP10.

This could come in handy if, for example, you only had enough Avios for a one-way flight or can’t get availability on your dates.  One-way deals in the other direction, from the US to UK, are more expensive but may still be more attractive than a one-way redemption ticket given the high taxes and charges added by both Avios and Virgin Flying Club.

You will be routed via Porto or Lisbon.  You can add a stopover here if you wish for the same flight price, although obviously you are responsible for your hotel costs.

TAP has recently taken delivery of A320neo, A321neo and A330neo aircraft (it is the first airline in the world to operate the A330neo).  Porto to New York is on the single-aisle A321neo, albeit still with flat beds in Business.  You can find out more about the TAP neo fleet here.

TAP also flies to Boston, Miami and Toronto.  The deals are not quite as good – London to Boston is £815 one-way for example – but still worth a look.

TAP Air Portugal is a member of Star Alliance so your flights will earn miles in any Star Alliance frequent flyer scheme.

Your best option to maximise your miles when paying is American Express Preferred Rewards Gold.  This offers double points – 2 per £1 – when you when you book flight tickets directly with an airline.

How to earn Star Alliance miles from UK credit cards (March 2025)

None of the Star Alliance airlines currently have a UK credit card.

There is, however, still a way to earn Star Alliance miles from a UK credit card. 

The route is via Marriott Bonvoy. Marriott Bonvoy hotel loyalty points convert to over 40 airlines at the rate of 3:1.

The best way to earn Marriott Bonvoy points is via the official Marriott Bonvoy American Express card. It comes with 20,000 points for signing up and 2 points for every £1 you spend. At 2 Bonvoy points per £1, you are earning (at 3:1) 0.66 airline miles per £1 spent on the card.

There is a preferential conversion rate to United Airlines – which is a Star Alliance member – of 2 : 1 if you convert 60,000 Bonvoy points at once.

The Star Alliance members which are Marriott Bonvoy transfer partners are: Aegean, Air Canada, Air China, Air New Zealand, ANA, Asiana Airlines, Avianca, Copa Airlines, Singapore Airlines, TAP Air Portugal, Thai Airways, Turkish Airlines and United Airlines.
