I'm not someone who travels in business class regularly, but for our honeymoon, my husband and I wanted to treat ourselves. Since we chose the more affordable destination of Vietnam and went for 10 nights rather than two weeks, we had more budget to splurge on traveling in style. So, we booked business-class flights from London to Ho Chi Minh City via Doha with Qatar Airways. Sure, the flights cost more than our actual honeymoon — they would've been around $10,000 before credit-card points —
