My wife and I fly often, but not considered frequent. We have several times booked flights through Travelocity. This trip, however we had an unpleasant surprise. We were booked to Nashville via a different airlines which went smoothly. However, upon return we were on United Airlines. When we were checking in, we were told that due to us booking "economy" class we were not allowed the usual carry on plus one personal item. We were then required to pay $30 per bag whereas on ALL past flights on any airlines, we were able to have a carry on bag. This was not made clear on the booking site as we would never have accepted that. What made it worse, we were on our way home and had no choice but to pay. My complaint is that was not made clear on the booking website. Even if it was listed (I'm not sure if it was) we don't look into the detail for "checked bags" as we never need to do that. Please make this United Airlines nickle and dime program more clear to your customers. Help us clarify these petty airline programs so we can make a more informed decision on the airlines we choose. Thank you for your attention to this.
