tap air portugal business class or united premium economy?

I’ve been planning my first big international trip, flying from Chicago to Lisbon, and I thought I was all set with a business class ticket on TAP Air Portugal. But after poking around online, I started seeing all these mixed reviews—especially about their carry-on baggage rules. Some folks say they’re super strict, and now I’m worried I’ll get to the airport and have to check my bag at the last minute. That’s the last thing I want after spending so much on a business class ticket! Meanwhile, United’s premium economy is a few hundred bucks cheaper, and I’ve always had decent experiences with United domestically. But I’m not sure if the upgrade to business class on TAP is really worth it, especially if the service or seats aren’t much better than United’s premium economy. I know TAP uses the Airbus A330 NEO or A320-200, and United’s got the 747 or 767 on this route. I keep thinking, am I overthinking this? I just want a comfortable flight and not to be stressed about my luggage or end up disappointed after all the hype. Anyone else ever feel like the more you research, the more confused you get? #airtravel #businessclass #premiumeconomy #Travel
