Is it ALWAYS acceptable to wear pajamas on a flight? No, it’s sloppy, says AMANDA PLATELL. Yes, they are stylish says ALEXANDRA SHULMAN…

Money is not coming in. Well, actually, of course, starting with the private jet, the flashy wristwatch, the designer sunglasses. And that’s before we get to the pajamas.

But the question is, is it acceptable to walk through an airport in your pajamas? Is Manchester City footballer Erling Haaland guilty of dragging us down a slippery slope in travel clothes? Or should we celebrate his panache, his confidence, his fashion sense? Here are two opposing views…

No, it’s sloppy, say Amanda Platel

He may earn close to £900,000 a week, but turning up for a flight in £1,000 Dolce & Gabbana pajamas shows that Erling Haaland has no class, even if he’s on a private jet to Monaco.

It also responds to an alarming trend of travelers showing up at airports looking like they just fell out of bed.

On a recent trip to Ibiza I couldn’t believe the state of my fellow passengers getting up for the 6am flight. Yes, we all had to set our alarms for sunrise, but out of sheer self-esteem there is definitely time for a shower and a quick change into clean travel gear.

Why do people think it’s acceptable to look like an unwashed slob when the staff who check our tickets, serve us in duty free, cook our full English breakfast and look after us on the plane are all dressed in their uniform, smart as a pin?

It is disrespectful to them and to you. Even after 40 years of traveling from here to Australia and back on 20-hour flights, I wouldn’t dream of turning up in my pyjamas, even if they were studded with gold.

I’m not saying we should go back to the BOAC days when passengers dressed up like they were going to a fancy dinner (although that would be nice), but what’s wrong with some Sweaty Betties and a loose top?

Coincidentally, as a seasoned traveler on long and short flights, my favorite outfit is a smart casual coat, scarf, jeans and t-shirt, which I also feel comfortable wearing when I arrive at a decent hotel after the flight.

Wearing pajamas on a plane is simply boring.

Yes, they are stylish, say Alexandra Suman

Not long ago, I was told by a travel PR that the number one rule when it came to wearing upgrades was don’t wear jeans. I wonder if they got on board with the message that pajamas are now acceptable.

Or they are, if they’re the right pajamas, because pajamas aren’t just sleepwear. Platinum blonde Manchester City forward Erling Haaland certainly has a runway-worthy collection, including several pairs by Italian designer duo Dolce & Gabbana who have led the movement in sleepwear that can be found anytime, anywhere.

But he’s not the only one who succumbs to the allure of this look. It’s no longer difficult for the rest of us to pull off, meaning you can travel in the same stylish comfort, even in seat 23D instead of the cream leather cocoon of the other breed PJ (private jet). Pajamas have hit the red carpet these days, so there’s no reason to avoid them when you travel, but they should have some panache. In other words, they should be worn with confidence and not as if the wearer forgot to set the alarm in time for check-in.

Flawless and wrinkle-free colors or a strong print are the way to go. And they definitely shouldn’t be that kind of pullover and sweater style. And, God forbid, not a cartoon character either.

As a modern two-piece suit, it is simply a plus for comfortable travel.

So much better than being in tight pants, leggings which are always a style zero zone, or shorts (especially for men) which I find much baggier than sleepwear.

Accessorized with styled hair (like Erling), shades and chic carry-on, pajamas are definitely a serious option for travel.

But when it comes to shoes, fluffy slippers are still a no-go area.
