My only complaint was that there was a threat that we, econiny fliers with travelocity, would not be able to take on luggage. She (ticket agent) added that we could only carry on one item that was the size of a purse. I never saw that notation on the website to

Flying Tips & TricksHow do I find my flight number?
  • When you've finalized your booking, check your emails for your itinerary. Your flight number is written in this document. You shouldn't have too many difficulties identifying it — just keep your eyes peeled for a code consisting of numbers and letters. The first one to two letters and single digit are called an IATA airline code and indicate the airline you're traveling with. Following this are one, two, three or four figures which make up your flight number.
How early can you check bags for a flight?
  • To have plenty of time to drop your luggage, clear customs and turn up at the correct boarding gate, head to the airport around three hours before an international flight. For a domestic flight, show up around two hours before. Even if you've already selected your seat and received your boarding pass online, it's worth noting that there are closing times for baggage check-in. It's one hour before departure for international flights, and 45 minutes if you're traveling domestically. Of course, times can vary between airlines, so it's a good idea to check these details when you book.
