I booked a round trip from Atlanta to Newark on Delta with travelocity only to have the return flight on United Airlines. Delta was awesome, United forced me to check in my carry on bag that easily fit in the over head and charged me an additional $35. The lady at United was rude and said it said on my ticket I couldn't carry on. The problem is they wouldn't let me do online boarding so I couldn't get a ticket till I was in the airport. I also booked a hotel in Newark at the Crown Plaza in Elizabeth. The floor I was on must have been used for prostitution or who knows what. The hall was loud and noises till 2am. One guy had his small 2-3 year old up and down the hallway till 2 am. Told the staff but nothing happened. Horrible! They might want to look into that for child trafficking.
