Spend any time on these forums and you see many forum members promoting travel in the fall and spring months. But you also see discussions here and elsewhere about how crowded Europe is this summer and about cities like Barcelona and Amsterdam taking steps to curtail the number of tourists who visit. And if you check the airfares for flying to Europe in 2024--I have Delta in mind--the fare increases after February are staggering.
Admittedly, some, because of children and work obligations, have to travel in the summer months if they do. But I wonder whether crowds and pricing will cause more to travel later in the off-season months and whether travel in the winter months will increase dramatically. Again, I understand that the winter months do not work for those wanting to visit towns and rural areas in some countries. But they would seem to work in the larger cities and southern Europe.
