Dubai, for instance, is available in Business Class for €1,164 / £1,042. As you can see from this screenshot (click to enlarge):
…. you can even get this price over the peak half-term week in October.
It is also worth getting a price if you are looking at routes to Asia, India or elsewhere in the Middle East, although Dubai seems to be the outlier in terms of value.
You can’t earn Avios or BA tier points from Oman Air, but they are an Etihad Guest partner and you can credit your flight there.
If you don’t have a credit card with 0% foreign exchange fees, your best option for paying is American Express Preferred Rewards Gold which offers triple points – 3 per £1 – when you book flight tickets in a foreign currency. This is because the transaction triggers the ‘double points for airline spend’ and the ‘double points for foreign spend’ bonuses.
The Oman Air booking site is here. These current Paris deals are bookable until 14th July.
