I have never checked a bag for a flight in my life and I never will. But then I also did two weeks vacation in Europe and stayed within Virgin’s 15lb carry on weight limit.
Check a bag if that’s ok (for me it isn’t so much the risk of having to wait for the bag at the carousel as not wanting to deal with lost bags) for you or don’t. But for the love of god everybody, you are almost certainly not moving wherever it is you’re flying to and therefore it is unnecessary to bring everything you own.
If rain at your destination is merely a possibility, you don’t need to bring an umbrella. They sell those around the world. If you expect it to be 80 degrees you don’t need to bring a heavy coat just in case. You don’t need to bring a shower head with you (one friend did that in case he didn’t like the shower head in his hotel).
And if you’re luggage is never more than you can comfortably carry, getting around at your destination is so much more pleasant.
